Hey all,
Funny story, working under the car today going to remove the alternator pulley (yes it’s underneath) to machine the pulley down further I noticed the cable from the alternator was very small (8mm2).
That was half my trouble!
When I fitted a CRV starter motor I deleted the starter solenoid and ran the battery cable direct to the starter motor as per the CRV instructions? and ran this small cable back to the alternator.
I stuck my head over the fence to see my neighbour who’s a leco and said this would support much amperage would it!
So I connected the battery cable direct to the alternator and then ran a 35mm2 cable to the starter motor, in doing so removed about 500mm of excess cable.
After completing that job I tested it again and with two fans running the engine ran fine!
But when I turned the headlights on the engine stopped.
So, tomorrow’s job is to machine the alternator pulley down to 48mm and check the thermo fans amp draw with the cable clamp multimeter I bought from Jaycar.
Just checking on eBay the fans draws between 17.5-29 amps, I was working on 19 amps, but worth it, they blow like hurricanes.
Cheers Phil.
