I have a '90 nissan pickup. I want to debug a sluggish starter. I'd rather not have to drag the DSO out into the garage to measure the current and voltage drops. If I could prevent the car starting for a second or two, I could easily use a clamp-on meter.
In the old days, I'd just disconnect the points... or put volts to the starter relay. I'm afraid of doing something that will cause some component to fail or put the ECU into some mode it takes the dealer to get out of.
Are there any simple/safe options?
