electrical help - fan, horn, blinkers, temp

[agr071]

When I press horn pad I can hear the relay clicking but no horn noise.

If the horn relay is clicking when the pad is pressed, it means that the relay is getting the earth from the horn pad. Therefore you MAY have a horn issue OR where it mounts to the nosecone.

heater fan and temp gauge are not working. Fan did not work pre conversion. I've tried other senders and gauge. I've also tried two other fan switches. Temp wire from harness jumps around all over the place from 1.3V to 9.5V with ignition on (don't know if this is abnormal).

Common issue for fan not working is the earth wire going to the fan body is loose.
With the gauge, you may get that variance in voltage because of the pulses from the voltage stabaliser. Not sure now but I think if you earth the temp wire with a test light, the gauge will read hot.

Lastly, is the column a WB one (with hazard switch) or HX/HZ one?

thanks heaps agro.

yes, WB column with hazard button (although it is temperamental and doesn't like to stick on without some convincing)

I'll clean earth on nosecone or maybe shift earth as the battery is also earthed to nose cone and i'm not exactly having a win at the moment.

NOTE: I put a fat ass +VE battery to starter cable on and the indicators started working again. I'm in the throws of making a -VE which is obviously even more critical. I'm hopeful for some miracles

I think the starter could be earthed better too - anyone have any tips or tricks with this? It's a smaller cheap as chinese type starter
