Planning my British wiring harness install
« on: Sunday,August 19, 2018, 09:25:00 AM »
I’m tracing out the circuits for my 68 S2 non federal car. I’m going with an 843 crossflow engine with carbs.  The British wiring harness is stock for a non federal 68 S2.
Would I still use the stock 10 volt stabilizer , regulator, and relays.  I’m thinking the engine builder -Alpine America - will provide the alternator, coil , and starter/solenoid combo.   Any advice is greatly appreciated.     Tom

By 10v stabilizer, do you mean the instrument voltage regulator?  If so, yes, unless you change the dash instruments.

Let us know what you end up with for ignition coil, etc and then I can give you specific advice for each piece.

Thanks John. Instruments are stock except speedo is a gps unit.  Not sure what this 10 volt stabilizer is. I’ll post a picture.    Tom

It's for the temperature and fuel gauges.  At idle, alternator output is low, and these two gauges use low impedance sensors, which means the readings would fluctuate if they were powered by system voltage.  Knocking the supply voltage back to 10v means the readings stay consistent regardless of changes in system voltage.
