I tried the meter, but couldn't get sane results, must have been bridging contacts with my probes.
Part of the problem working back there is that my eyesight ain't great. I had better luck using my phone to zoom in so I could see that there was a gap.
Working alone on these things is a pita too. Tried to jerry rig a setup with jumper cables so I could bump the starter, but mine were way too fat to be practical. I'll probably pick up one of those bump switch thingies when I get a set of SAE wrenches.
