Alternator question
Ok so spent some time under hood tidying up wires. Removed 12v choke wire from ballast resistor. Removed choke last year.
Started car up, battery 12.73 Volts, 12.6V alt stud to ground.
Shut car off, general underhood tidy up, go to start car, cranks but no start, as soon as I let key to run position it fires, and is running. Weird? So shut car off and restart.
Same result if it makes sense, "turn to start", it cranks but just cranks. As soon as I let key return to "run" position it fires up and stays running/idling.
But volt gauge now reads 11V.
Battery voltage 12.5V
ECU case to batt.+ve 12.4V
Rev car up in park, voltmeter now only rises to 12.1V. Before it was revving up.to 15V and dropped as rpm dropped.
I dont trust to take the car for a run as I dont have good known spare VR Ecu etc.
Suggestions?
Thanks all.
You very likely are suffering what I touched on before.........voltage drop in the path from battery, through bulkhead/ key/ connectors and back out to the ignition.
