positive to negative earth conversion

The engine and gearbox is bolted in its final place.


To attempt to start it I needed to convert to negative earth for the starter motor and alternator.
Just turning the battery 180 degrees was almost all that was required. (and changing the battery connnectors).
This page about positive to negative conversion gives more details and ideas on how to connect an alternator  via the regulator box.



When The wiring is finished I will connect the Alternator output direct to the starter motor positive feed which is direct from the battery. I moved the main starter feed at the old solenoid so the original output was now combined with the battery feed. The solenoid output then is only a small wire to feed the V6 starter solenoid.



The Huco sucking fuel pump was fitted in the engine bay and connected to 12v.

The Capri wiring loom loosely placed in situ and the engine was test started.
It was pleasantly loud with no exhaust and proved the circuits are all correct.

The clutch pedal was tried and seems to not be working. The lever moves about 10mm. Will need to adjust and test again.

Later I realised the clock wasn't working and the extra electric fan was spinning the wrong way.
The clock had been modified by a previous owner so the wires were swapped and its all ok now.
The fan will have the wires swapped also later.

Next plan... fit radiator and fill with water.. check clutch

Merry Christmas

Post Christmas update - Capri wiring loom now modified and connected through the bulkhead. The Duraspark unit is in the Passenger foot-well along with a new 4 way fuse unit. This fuse unit currently supplies 12v to the ignition and the tacho. Later it may supply power to any other new ancillaries...like a Radio or the heater fan.
Clutch checked further - still can't release.
