Hi everyone. First of all, thank you for your help so far. I promised an update so here it is. The starter motor is getting 12 volts, at least as far as I can tell. So far in testing in the “On” position, there is 12.5 volts. It’s very hard to read when the engine is cranking to start, because the starter motor shakes a lot and I have to crawl under the car and reach up awkwardly to get to the starter motor. To get an accurate reading when the engine is cranking, I will need to get some copper wire and twist it around so it can remain in contact while starting.
To the best of my understanding, the fact that the starter motor is getting 12.5 volts seem to shift the probability of the problem to the actual starter motor and solenoid itself (is the solenoid separate or inside the “starter motor” that I see under the car)?
I suppose there’s some chance there’s no drop in current but a loose/frayed connection that isn’t able to carry enough current, or perhaps the power relay could cause this problem as well, possibly??
One other thing I noticed: when connecting the negative to the frame of the car, the voltage reading was about .22 volts. When I read it connecting to the starter motor case, it was 12.5 volts.
Also, my car is a Kia Pregio van, from outside the US. I’m from the US but an ex pat. Some of the writing (including next to the key ignition barrel) is in Korean, that’s where the question from on and start came from, just wanted to be 100% sure
Ok thank you again guys and any help is much appreciated. I’m tempted to go to a junkyard and try to pull off an old starter motor and put it on my car. I’ve never done this before, but I imagine I can figure it out.
