Clark C500 SERIES:
Clark C500-25 Forklift ignition not spark

Hi everyone,
I am back again with another problem after replacing spark plug and point inside the distributor cap. The forklift was hard to start for few weeks, so I decided to get the Clark tune up kit and begin to make my replacement. After the change out tune up, the lift start up right away. Then I decided to replace the temperature gauge on the lift due to it wasn't working, after removing it and waiting for the new gauge to come in from Clark's, I went out and try to crank the fork lift now it will crank but will not spark. I have a spark tester inline on spark plug, but cannot see any spark. I have 12.49 volt at the coil (+) and roughly 10.34 volt out of the (-) side. The gap point set at.022 and spark plug set at.025. Anyone whom have ran through this problem before, please shine some light into what I did wrong, that causes this no spark problem.

The capacitor (condenser) is new and check to grd ok. I just went to check continuity grounding against Coil case to any metal parts of the body of forklift, that check out good. This is how I have the ignition coil and distributor wires: from battery (12+) go to starter then from there it goes to amp/volt gauge black 10ga wire, coming out of the amp/volt gauge red 10ga wire go to alternator, there's also another #12ga red with white go to ignition switch, so everytime I turn on the switch 12v power provided to the (+) side of the coil this also provide power to turn on the LP coil to open up ( not sure if this is right) but it was my thinking that if I provided power to both the coil ignition and to the LP coil if I have spark it would get combustion. So not sure where I went wrong on this. Any Help to clear this problem would be greatly appreciated.

you don't mention the capacitor inside the distribor cap, it needs to be well grounded as does the coil case. the voltage on the side of the coil that goes to the distributor point (-) should vary from near battery voltage to shorted to ground as the points open and close.
