[QUOTE="ionbeam, post: 828075, member: 277"] Needle type meters need to be correctly zeroed and the voltage scales are not so straight forward. When using any meter not all grounds are created equal; you can get a number of different battery voltage readings depending on where you choose to put the black meter lead. Or, the meter may indeed be BORKED. The worst place to hook the black meter lead -- anywhere on the front fork area, and the rear sub-frame is almost as bad. The main frame is fair to OK, the engine block (not cylinder head) is good but the battery negative post is the best. If you are troubleshooting the charging system the very best place to hookup the black meter lead is to back-probe the connector directly on the R/R. Since the coils will not fire or not fire well at 8 volts and the starter relay coil will drop out around 8 volts (the relay will go CLICK-CLICK-CLICK and the engine will not spin) I doubt the reading is correct or I misunderstood what was being reported. Edit: Or, Zork is a couple o' lemons short of a full charging system. [/QUOTE]
