Dick,
Thanks for the responce. I put a test light on it today. I grounded the
test light and here is what i got. The bulb was bright on the armature and
the bulb flickers on the field at both the generator and the voltage
regulator. Can the brushes be damaged? I went for a drive down the freeway
and the ammeter shows it charging. When I slow down then it stays a litttle
on the discharge side and its like it gets stuck. When I kick her in to
passing gear it starts to show a charge again until I slow down to a Idle
position. Maybe the brushes are not making good contac, could I have melted
one or something? The battery was really low. I am charging it now. Its
brand new 27 group deep cycle battery.
Thanks
Tim

Once you have cleared the short, the spark should be gone also. This
episode shouldn't have hurt the voltage regulator, unless it was left
connected for more than a minute or so with the current flowing. If it was
left connected longer than that, the regulator may have been damaged, but
the symptom will be that there is no charging going on. So if your tapping
on the gauge brings it back to life, you can check for that. If the gauge
stays stuck, you can always check for charging by starting the engine, then
pulling off on battery cable. If the engine keeps running, the generator is
charging, at least a little, so you know the regulator is somewhat
functional.
