Alternator not charging

OK found a good photo of your meter on ebay, lol.

First you want to check the field for shorts. With the probes into their "normal" spots, the two far right hand jacks, and the switch set for ohms (200 at top left) measure from each field terminal to ground. CHECK the meter by shorting the probes which should read near zero. When checing the field terminals to ground, want the OPPOSITE of this, that is, infinity, or open.

If that checks out, measure field current...............


I'm guessing? that when you put the switch in the high current position (in order to measure amperage) that it mechanically uncovers the two jack positions on the left? To measure current in this case, you would set the switch toward bottom left to 20 in the blue (which is DC) and not 20 in the white (which is AC)


You would want one probe plugged into the far right jack (common) and the other into the far left jack (max 20A fused). Always hook an ammeter in series, not across, as you would a voltmeter.

In other words you would have a clip lead at ground-----other end to one field. Second field to one ammeter probe, other ammeter probe to the starter relay.

Notice that the jack says "max 20A fused." These use a special internal fuse, that are fairly expensive, several dollars each. So at least the meter is fairly protected
