That voltage regulator, wiring mess i had was straightened out. All the wires from the generator to the voltage regulator had continuity. I wired the amp gauge correctly as John t and JMOR instructions.Voltage at battery read less volts engine running than shut off. Replaced voltage regulator and am now getting 14.4 or so volts with engine running. The amp gauge needle is quivering like a flag blowing in a hard wind. Is the quivering amp needle anything to be concerned about? Thanks for your help, one more little problem fixed.
 
Ive seen ammeters do that, often they were old and corroded but if not, things such as the gennys commutator section mica seperators werent properly undercut causing brushes to bounce,,,,,,,,,,,or brushes were getting too short or,,,,,,,,the brush hold down springys were weak or sticking,,,,,,, or VR relay contacts were burned and carboned,,,,,,,,,or bad connections or grounds.......I wouldnt worry for a while maybe the VR contacts will settle in or the brushes will settle down.

Glad you got it going & thanks for the feedback.. I have an old Farmall that has the quivering ammeter and has kept batteries charged like that for last 25 years.
 
nervouse ammeters can be something or nothing. can be a ssimple as a cheap non dampened movement.. or as said with the vreg, brushes.. etc.

one quick test is to full field it. while driving over pasture. if it jiggles at the top end of it's movement.. it's a nervous ammeter.

if it bounces wildly.. it could be a brush or vreg contact issue.

I've seen some pretty JUNKY vregs before.. even new ones. I bought a repalcement for my IH H and the contacts didn't even strike SQUARE...
 
I'm a pretty simple guy, so in this case, if the battery is staying charged, WGAS?
 
yep. problem can't be too bad if the battery charges and doesn't overcharge or discharge overnight..e tc
