Derek,
There are two wires which go from the regulator to the generator. One
goes to the D+ terminal and is the "armature" lead. This is the one that
delivers the current to the battery, etc.. The other lead goes to the DF
terminal on the generator and is the "field" lead. Disconnect the leads
from the regulator. Get a voltmeter and connect it between the armature
lead and ground. Slowly rev the engine up to about 3000 RPM and see if
the output voltage from the generator increases to at least 15 volts.
(Chances are that nothing much will happpen.) Next, ground out the field
lead and do the same test. This should yield a significantly higher
voltage. Don't do this for long or you may damage something. If you find
after doing the second test that the ouptut voltage of the generator is
up around 15-18 volts (or more), chances are the generator is OK, but
the regulator is kaput.
You can try touching up the points in the regulator with some 600 grit
wet-or-dry sandpaper or a points file. Just make sure that you do not
alter the spacing between the contacts when you do it or the regulator
will over or under charge the battery. Clean the contacts again and see
if it works. Living in Victoria, i.e. maritime climate, you may have
some internal corrosion in the regulator that needs to be removed in
order to get the thing working.

HELP A few days ago my eld ceased charging. Charging light came on and didna go off. My first thought was regulator. so I first checked the ground. Had a good ground. I took apart the regulator, used contact cleaner, blew it out with an air gun and reassembled. Wowie zowie the light went out. A few hours later on it went. so I swapped it out with a different from another non running eldo. No change, red light stays on. So I swapped geerators. No change. I would like to test the generators, but, do not know how. Can someone give me some pointers. I tried going from the side with the two red wires to ground. No change with a running engine. Tried across the poles, didn't see anything. So, I'm stuck. Derek Hamlet Victoria, British Columbia |
