FURUNO 1623 RADAR

[geoff3nebel]

Bought it new from Cactus, I've just installed it and am 99.9% sure I've wired it correctly.
The screen fires up and menus are available.
The scanner turns in the radome.
Can't get a 'picture' though.
I've followed the set-up instructions (I think) several times but fear I might have missed something garingly obvious.
Idiot-proof advice will be gratefully received.
Thanks,
Geoff

It sounds as if it's in a "standby" mode. I'm not familiar with that model but is there a panel function to enable/disable the transmitter?

If the antenna is definitely turning, then the set is in transmit mode and you should get a picture. Have you run the diagnostics, section 2 of the manual? The only other suggestions are to ensure the brightness/contrast of the display are turned up, although if the menus are showing this is probably OK, and to make sure the cable connections are all good, by tightening the plug and checking the ones you've made in the radome. If these don't help, then you may need to get back to Cactus.
Add; The manual describes a voltage check you can do on the magnetron after installation, might be worth doing, but mine worked "out of the box".
Further thought, have you cut the cable to install it? This would be a very likely problem area.

I'm not on the boat, but will check on Sunday.
Thanks for raising the question.

[geoff3nebel]

Haven't cut the cable.
I have plenty of battery power - 4xTrojan T105 fed by 100W solar and Rutland 913.
I'll run the diagnostics in section 2 and a voltage check on the magnetron when I'm down on the boat on Sunday.

[geoff3nebel]

I'll check all the cable connections too

Further to my suggestion that your radar might be in "standby" mode, it would appear that this is the default on power-on. The rather obscure procedure for making it transmit is defined on page 3 of the operator's manual.
