AT ROPE'S END
Posted: Mon Sep 13, 2004 10:15 pm
I just purchased a 1952 PO said it was running good and he let it set up
for about 3-4 months and now it will not fire. This CUB has a 6v system
with a distributor and coil. I have checked the following with the indicated
results:
1). Compression [dry] 95 lbs.
2). checked wiring; found defective ign switch [ high resistance open]
replaced.
3). Found plug wire with defective end [distb end] - repaired
4). Checked and re-gapped plugs
5). Replaced the points and condenser [gapped to .020]
6). Check for voltage [with lead on + Batt post]
a. 6v on either side of coil
b. 6v in coil output to distributor
c. 6v to center contact inside of the distributor cap
7). Checked the wire from the condenser to the point
a. Not shorted to distributor housing or inside or to the
condenser case
b. Post through the distributor housing is insulated
. Replaced the rotor cap
9). Took coil off another tractor and put on '52 with no change then
replaced on other tractor and made sure it is still good. The donor
tractor started fine.
10). I do get an arc when the points are broken.
Is it possible the plugs are not grounded in the head? I should also say
that the dealer working on this CUB before me connected the Batt
negative to ground. I think I read someplace that this could destroy the
voltage regulator. Could this be happening? I burnished the points on
the relay going to the "L" terminal.
Any help is welcomed.
I am just about to my rope's end on this one.
