HJ47 glow plugs and lights acting very wierd

[cruiser60series]

My glow plug and tail light circuits are somehow linked at the moment. When the glow plugs are on my tail lights are on and when the tail/headlights are on the glow plugs are on.

I was recently driving a trailer with a dodgy tail light circuit. It kept blowing fuses and since I was driving through fog over a mountain at about 40km/h I decided (so i could be seen from behind) to jam some coins in my fusebox, allowing whatever was shorting to short. And my tail lights to work.

When I finished driving the car smelt like burnt plastic, the terminal connecting the glow plug strap to the input strap was burnt out. I've replaced all the melted bits and the glow plugs now work but the circuit is being wierd - as previously described.

At the time everything was playing up, EDIC didn't work, tail lights didn't work, fuses were blowing on the tail light circuit, dash lights went off.

There must be a crossed connection in some relay somewhere or something. I thought perhaps the tail light relay was playing up but I can't find one anywhere. It's in the wiring diagrams but maybe it doesn't actually exist.

Perhaps it's in the glow plug control unit, it's the superglow glow plug system

Any Ideas?

I am aware I could make a simple switch/relay set up for the glow plugs but since my car is in such nice original condition I would prefer to keep it that way.

only way i can think that those two systems could be connected, is that the wires have melted together in the engine bay.

trace all your wires in the engine bay, i bet youl find a loom thats all melted together.
