For those of you who love doing everything on your crabs except electrics here is a video that shows why your multimeter may give you misleading readings when you are checking power feeds.
Ignore the title of the video, that refers to the second half. I suggest you watch from 4 minutes to 14 minutes and ignore references to sophisticated test gear, you only need a bulb and some wire. The bottom line is that the multimeter may read the correct volts even if there is a poor earth or other connection but there is not enough current to operate headlights, the coil, wipers etc.
Hope someone finds it useful, video here
