OK folks, you know I had issues coming back from the IR on my 88 .
I bought a new battery (acid filled...but any port in a storm!) removed a bunch of fuses and made it home ok.
Now the Electrics family and me are not the best of friends. I'm not even really positive I'm using the correct settings on the admittedly cheap multimeter I'm using (see pic)
I'm going to relate what I've done in detail so perhaps you can tell me what these results actually mean.
Fully charged and no load, using the 20 volt setting I get 12.62 across + and - terminals of battery.
With no headlight or tail light on (fuse removed) I get 13.1 at idle and 13.9 v at 4000 rpm...again, across the battery terminals
The resistance test and the ac voltage test were done with the plug disconnected
Doing the resistance test...
My meter has 200 Ohms as the lowest. Crossing the probes reads .7
between the pins got 1.2, 1.1, 1.2 so that means the actual ohms are .5,.4,.5?
From the pins to a good frame ground I got the same readings??????? (I thought it was supposed to be 0=open?)
Doing the ac voltage test...my scale is 200 (does that even matter?)
I got 20,21,21.5 at idle
and 65,72,73 at 4000 rpm ( research said should be more like 100-110 v ac)
So what I'm thinking is that the stator is working..... just too weakly?
Where do I test the rectifier?....or is that even a possible issue with these readings?
