HYDRAULIC SERIES TROUBLESHOOTING GUIDE
FIXING REVERSE POLARITY GENERATORS
(ONLY USED IF REVERSE POLARITY IS SUSPECTED)
If your unit is continually blowing the 30 amp fuse in the voltage control line, you could have reversed/negative polarity
generator. To fix this, you must have either a 12 volt jump pack or a 12 volt battery with jumper cables. Do the procedure on
the far left generator and then repeat the same step on the one right next to it.
THE 12 VOLT JUMP PACK OR 12 VOLT
BATTERY HAS TO BE IN GOOD WORKING CONDITION.
WHEN USING A 12 VOLT BATTERY
(WILL ALSO REQUIRE A SET OF JUMPER CABLES)
1. Hook the jumper cables up to the battery with the black clamp on the negative post and the red clamp on the positive
post.
DO NOT LET THE OTHER ENDS TOUCH, OR THERE WILL BE SEVERE SPARKING THAT COULD CAUSE
DAMAGE.
2. With the other end of the cables, take the negative black clamp and put it on a good ground on the unit.
3. Scratch the positive red clamp across the field post of the generator, which is the smaller of the two posts on top of the
generator. It is normal to see sparks while doing this. Do not attach the positive cable clamp; you must scratch it across
the field post.
4. Once you have done this a few times, you will have reversed the polarity back to positive in all of the generators, as long
as the wires have been hooked back up correctly.

WHEN USING A 12 VOLT JUMP PACK
1. Put the negative clamp to a good ground on the unit.
2. Turn the jump pack on while holding onto the positive cable. Scratch it across the field post on the generator, which is
the smaller of the two posts on top of the generator.
It is normal to see sparks while doing this.
Do not attach the positive
cable clamp to the field post as this may cause damage to the generator. You must scratch it across the field post.
3. Once you have done this a few times, you will have reversed the polarity back to positive in all of the generators, as long
as all the wires have been hooked back up correctly.
