1983 Estate with electrical problem

I'm going to now assume that this is a wiring problem and I have two questions for the list. Is it possible to find the plug connectors for the wiring harness from an electrical supply? I don't see my harness listed on any parts suppliers. Is it fairly easy to replace the ignition harness on these cars without to much trouble?

I think from meory that fuse 14 is fed from the dipped light circuit. Certainly on UK spec cars fog lights only work on dip beam. Fuses 15 & 16 have a common supply. If you look at the contacts on the fuse box the supply wires go onto the back set of contacts feeding the left hand side of the fuse. If I remeber correctly fuses 15/16 are fed from the light switch splitting circuits at fuse box so could be a faulty switch - pop switch out and check for voltage in/voltage out. The lack of dash lights may be an engine earth problem or there may be problems with the loom on the engine - they are known to be biodegrable! The engine loom has a multi-block connection on the bulkhead. Hope this will get you started on sorting out. You would find the wiring diagrams in the Green Book invaluable for this. Mike

Thanks Mike, it did help me get started. I have not been able to find an after market replacement for the engine harness so I've started replacement myself. So far so good. I've ohmed out the wire to the temperature sender, a yellow wire that goes to connection #2 on the plug. The very next wire I tried was the oil pressure sensor which I'm going to assume was a brown wire (tagged SB on the Haynes manual page 303). I traced it down to what I assume was the oil sensor on the front left hand side of the engine (beside the oil filter). The problem is that this sensor has two wires on it. The aforementioned brown wire that goes to the plug and a left hand connection that goes to where I do not know and looks like it might be a green wire? According to the wiring diagram the sensor goes through the idiot light and therefore is not a separate connection. Man these wires are in ROUGH shape making it hard to tell what original colour they were.
