240 battery drain

I"m working on a friends 240 that drains the
battery. Today I 1)Disconnected the coil,
2)disconnected the wires from the small post on
the starter relay and the link between the relay
and the starter, 3)Disconnected the generator
wires. The voltage regulator and generator look
fairly new and after removing the VR cover I could
see the points were both open. I think I will
disconnect the voltage regulator just to make sure
that isn"t it. The battery shows 6 volts and with
the positive cable removed I get 3 volts between
it and the battery post. Is this a positive or
negative ground system? When I hook the cable to
the battery, the ammeter does not move. Right now
it is neg. ground. If I remove the neg. cable
from the frame, the drain goes away. Next step is
pull up the instrument panel and check the wires
under there. What hydraulic oil does this take,
it"s low. Wiring diagram? TIA
 
A 3 volt drain will not move the amp meter it is not sensitive enough to show a draw at that level. It is not a radical drain, but it would deaden the battery in a day or two. Leave the volt meter hooked up then disconnect things (and reattach them if no change) Jim
 
That is a pos gnd system you need to check the Delce Remy gen and then see if the regulator is the Correct ONE FOR THAT REG. That is important as on the bottom of the reg it should say which ground that reg is made for. You will need to remove the reg as it should be marked for which ground its is made for. When you are correct on the ground and hook up the wires again you will need to polarize the gen to make sure everything is correct. Its possible he reg is fried by having the incorrect ground.
