Electrical Woes.

My 79 3000M is going through a rough time. The problem this time is with the electrics. When driving, the ignition light illuminates and as a result, I lose partial electrics. On investigating this problem I found that I had lost two circuits all together. The first is the circuit which provides 'Stop lamps, reverse lamps, windscreen wiper, heater, windscreen washer, temperature indicator, fuel indicator' the second is the 'turn signal indicator'.(the voltmeter also reads zero, but the car starts and drives fine) I have took those straight from maintenance manual. It states I should have two fuse boxes, top and bottom, however I have a single fuse box housing four fuses. As I know my hazards work fine, I found the associated fuse and replaced that with the three remaining fuses, all fuses operated the hazards. I removed the fuse box and all connections to it are made and firm. I have found two earth points, one either side of the engine on the chassis rails, these are tight however slightly corroded. I am wondering if there is an earth point further back, perhaps underneath transmission tunnel or towards rear of car that could be suspect too? I am hoping both circuits run to the same fault, so fixing this fault will fix both circuits? fingers crossed!

My wiring is a mess and its on the to do list this winter. The car is booked for its MOT tomorrow but this can be easily cancelled, my main concern is the pre 80's gathering as I wish to attend this in the M and that be the last event before a body off starting in the winter.

Where is the rear earth location? I will check with a multimeter the first fuse point. I thought the hazards were on a seperate circuit, the 'turn signal indicator' on a circuit of its own? I have a relay for hazards and relay for indicators, I've switched them round and they both seem to be working fine.

The frustrating thing is everything is wired up but I have half as many wires again running alongside the loom which aren't connected to anything. The wiring loom is so tight that any slight tug is enough to brake a corroded connection. I really need to solve this.

Well I have cleaned up all earths to a shine, the two either side of engine and the one near fuel tank. I have checked all fuses and all connections are made and tight, yet the problem still consists. With no clue as to what is wrong and the car outside of it's MOT I will have to miss the pre 80's. On top of this I strained ligaments in ankle and can't put weight on foot never mind press the clutch!
