You've had an uneventful passage across from Salcombe. You left at dawn, and are now making an approach to Guernsey, for an approach to Beaucette, north-over the island. It's your first passage to the Channel Islands and you are feeling good about having a plotter with electronic charts - far more charts than you'd normally have spent out on and no uncertainties of position. As you near the north end of the island, with the currents starting to run strong, you decide to take the sails down and motor; there isn't much wind left and it will leave you free to concentrate on pilotage.
After you start the engine you notice that instrument bulbs seem much brighter than ususal. You make a note to check it out when you get into harbour and go back into the cockpit. Just as you are arriving at your waypoint to alter course down the Little Russel the plotter screen goes blank and the engine note changes. The autopilot goes off line and you have not remembered to make a note of the last heading the autopilot was steering to maintain track. You glance at the magnetic compass and ask your crew to maintain that course.
You go down below and are immediately struck by an acrid smell of hot PVC wiring. You get a deep, hollow feeling in your stomach. This can't be happening? All of the electrical circuits are dead. Nothing electrical is working and the voltmeter is reading zero. You check the fusebox and all of the fuses and breakers are fine. You check the batteries; the smell of acrid, hot, PVC is much stronger down there but there is nothing remarkable to see - it all looks in order. You have a look in the engine compartment and apart from the smell, all seems normal.
Your crew calls to ask what you want her to do. The present heading is taking her towards a lighthouse and some rocks, and by eye alone she is crabbing by nearly twenty degrees as the current starts to take you down the Little Russel. The problem is how is the channel marked? You'd had it all laid out on the plotter - painstakingly laid out with waypoints and the alternatives of Beaucette and St Peter Port. You don't have a pilot on board - this was one of the cost-savings that allowed you to justify the price of the plotter and electronic charts. In fact, the only charts you have on board are in your plotter.
Your autopilot is dead, as is your VHF radio. Your crew is not experienced at steering a good course by hand and in any case you have no charts on which to lay off a course.
What do you do now?

Thanks for reminding my of why I chose to stick with paper charts a mechanical log(backup) and a batteries operated sounder!!

sails up sharpish, engine and batteries off and i'm not an idiot so I would have charts and pilot available, get crew to launch and lash dinghy to side of boat, outboard running to give some steerage if wind has failed, get anchor / chain ready to drop if needed, ditto kedge, get crew to make a cuppa.

What if you don't have an outboard?I don't. A handheld VHF would be a good thing to have I was thinking...

oars man!, as a frightened man with a a bucket is worlds best bilge pump so are oars the best form of propulsion (any way I have 2 dinghies and two outboards on board so ya boo sucks)

OK I'll bite. I haven't checked practicality of the passage so I'm taking info at face value.
Should be still daylight (assuming summer passage) for long enough to get into St Peter Port. Forget Beaucette.
Orientate yourself quickly with aid of Little Russel chartlet from Reeds which has sketches of main nav marks. If not, from memory of your preparation, you'll remember what Platte Fougere looks like won't you? You should aim to leave this well to starboard.
My guess is you are heading towards Grande Amfroque and need to turn sharp right onto a course of about 200 deg magnetic to pick up the leading line of Roustel and Brehon Tower - the latter is the key mark. Steer so as to maintain open water between Brehon and St Martins Point (at the SE corner of Guernsey). Once past Brehon (leave it well to port), steer to make good a course towards Castle Cornet on the south breakwater which will bring you to the harbour entrance.
Of course you'd worked out all this beforehand hadn't you so all you had to do was read your pilotage notes.
As to your engine, if nothing's actually on fire, I'd be inclined to keep it going until I no longer needed it. If it's a diesel it won't need any electricity.
One important point, with the tide running in your favour at up to 5 knots, you won't have long to sort all this out - so get the pilotage sorted out first - then put the kettle on/ get out your spare handheld GPS and enter a useful WP/ fix the electrics later.
Once you're settled on your heading down the Little Russel, you'll probably see other vessels ahead of you on much the same course. Use them to help identify the main marks. But beware, if they are going to Beaucette you'll end up on the rocks if you keep steering to follow them.
No doubt there'll be plenty of other advice if I've got anything wrong ....

I would firstly turn around and head for a known safe area to stand off.
Being a leccy the first hint was bright lights. Obviously the alternator regulator has died. (it happened to my son's car a while back resulting in damaged gear and blown fuses and globes. It went to 17 volts) So, stop the engine and disconnect wires to the alternator. Start engine again hopefully the engine system is not dead. It may have been prudent to try to disconnect the alternator without stopping the diesel engine. Certainly reducing revs should have reduced the problem. From here it would be a case of replacing fuses to see just what electrics are available. If wiring is so burnt as to have fused the wire itself or ruined switches then you might have to think about a temporary wire from battery positive to the chartplotter. Obviously you would be busy with the multimeter or test lamp finding just where the power has gone. Hopefully not all batteries have been ruined by the voltage excursion. Of course you know the whole system very well ie locations and connection arrangements.
If all electrics are unavailable then you will have to rely on what charts you have and your compass. If pilotage is difficult/ risky then you must return to an area/harbour you know you can safely enter.
Just talking to a friend last Saturday who experienced something similar while doing a delivery job from Croatia to Fremantle on an ex charter Bavaria 42. Being new to the boat and not a leccy he was pretty lost with no electrics or auto pilot but they did find their way into a harbour (Exmouth) (no not the one in UK)(and that wasn't the worst of the problems) There is no substitute for your own knowledge of the system and how it works. Both engine and electrics. olewill. (ps leccy = electrician)

Keep engine running unless fire risk. Easier to fix electrics later than deal with fire or hole in boat if aground! Always have a back up plan that is not dependant on the master plan. ie handheld GPS pre-programmed with the same way points, HH VHF, paper chart - No comprimise on safety. All part of passage plan (basic RYA stuff?)

if you don't have a bearing in your head for a safe course / stand off location you should not be skippering the boat. furthermore you should have a paper back up, hand bearing compass and hand held gps available. if not, well you deserve the rocks.
personally i have a spare fused power supply direct off the main battery for my autohelm on a long lead. paper chart/hand bearing compass & spare batteries for the handheld gps.

Interesting food for thought.
As I have hand held chartplotter, HH VHF, HH GPS, handbearing compass and paper charts I would not feel that the navigation or pilotage was the greatest of my concerns.
I would be more concerned about control of the vessel. If there was enough wind to sail, obviously I would sail - anywhere I could that would keep me off the rocks. If I couldn't sail (no wind or wind and tide pushing me onto rocks) I would either call the coastguard for advice or send a Mayday depending on how dire the situation looked. I'm assuming anchoring is out of the question.
Somehow I don't think there would be enough time to inflate the dinghy and lash it to the side of the yacht. And I wouldn't think my 2hp would be much use anyhow.
Actually, I don't think I would be there in the first place. I would be pretty terrified at the prospect of a 5 knot tide and all those rocks. Give me the East Coast any day!
