Help with electrical problem

For some reason, my high beam & oil warning lights are not working.

I wired up some after market warning lights that worked okay, but the wiring was too long. After I shortened them, (same connections as before) the neutral, indicator & oil lights worked but the high beam didn’t. Took the sub-loom off to check the connections and put it back on.

When I turned on the ignition, I noticed a small puff of smoke come from under the left side of the fuel tank, so immediately turned the ignition off. Tried again, no puff of smoke but no oil warning light either now (as well as no high beam)

I have checked the fuses and they are okay but am worried about where the smoke came from - I can’t see any burnt wiring, even on the oil pressure switch connection so assume that it must be something in the main loom.

Can anyone offer any advise before I dig any deeper??

Thanks

Have you tested the fuses or just looked at them?

You might have blown a wire, which isn't always visible.

Sometimes you can feel where the break is, either by a bump or that it bends differently to the rest of the wire.

But before getting carried away, I'd check for continuity from your connections to the lights.

You need to find where that plume of smoke came from. Something is burnt or melted.

Did you grease the connections before plugging them back in? I have seen in the past where white assembly grease was used instead of di-electric. The white grease burns when electricity travels through it, also it turns black and may lose the connection. I don't know if it smokes though?
NR.

Electricity shouldn't be passing through the grease. The grease is only meant to insulate/isolate the connector from the elements.
