Thanks, Richard and Paul.
Yes, I agree there are multiple ways to test the isolating diode in this case. The method Richard proposed is definitely the quickest and easiest way, without any foreseeable or potential harm here.
However, I'd be cautious about applying this method broadly. It reminds me of a mistake I made in the past: when installing a backview camera on my truck, I forgot it requires 5v DC, and I wired it to 12v through a 5 amp inline fuse that immediately fired the camera, and the fuse was intact.
Additional testing methods here, however, require you to disconnect the bolted wires or at other ends (at the batteries & alternator). Otherwise, readings can be misleading.
