Reloom Conundrum


Best Answer Ollie1953 , 23 December 2020 - 08:36 AM

You will need to check the following to determine if your loom is connected/manufactured correctly.

Disconnect the vehicle battery and use a continuity tester, a multimeter on the OHMS range.

Disconnect the wire to be tested at either end.

 

Check continuity from the starter solenoid to the light switch,  brown wire.

Check continuity from light switch to the two fuses, red wire.

Check integrity of these fuses.

Check continuity of the output wires from the fuses go to the side light and panel light circuits, think these are red/green and black/white wires.

Check continuity from light switch to dipswitch, blue wire.

 

Any anomalies from this will have to be traced and rectified.

 

This my understanding of the wiring circuit and hope it helps.

Many thanks for all your help. It turned out to be the replacement glass type fusebox had two terminals linked together on the backside of the box effectively linking fuses 5-6 and 7-8 together. Removing the link and problem solved.

It will be a merry christmas after all :xmas:

I am in the process of rebuilding a 1989 Mini Rose. I have replaced the main loom with a new item from Autosparks. My question is should the panel lights and sidelights come on automatically when the ignition switch is turned on. Everything else appears to work as I expected. The car is fitted with the dim/dip system that has the resistor on the nearside inner wing disconnected because I fitted relays and fuses to all the headlights.

Many thanks.

Nope. Only when switched on. The light switch is a double pole switch. Off/side lights and instruments/headlights

I have removed the lighting switch to check it is ok. It appears to be good, but before refitting it I switched the ignition switch to the first position and the side/tail lights and the panel lights came on!! Any ideas at this stage would be most welcome.

Sounds like theres a connection wrong somewhere as sidelights should be permanent live. Is your fuse box wired correctly?

Also make sure the pins are in the correct places on all the wiring connectors for switches and stalks.

I have checked the fuse box connections and all are as the wiring diagram. How do I know which colour cable goes to which pin on the wiring connectors as I can't seem to find a relevant reference diagram? Having looked over the wiring diagramit looks to me the only way for the side/tails and panel lights to come on is if fuse 7-8 is energised. Bearing in mind I now have physically removed the lighting switch and the dim dip relay I cannot see any way that turning the ignition switch on can cause the lights to come on and yet they do. Any help would be most welcome please.

You simply need to match the wiring on the loom to the wiring on the corresponding plug

I've heard mixed reports from autosparks looms. There may well be a fault

Unfortunately there seems to be no alternative so there's no competition.
