I am converting a 1951 Yale Forklift from 6v positive ground to 12v negative ground. I cannot get the spark plugs to fire. Yale Model #: KG51T-20H Serial #: 512736
Engine: International Harvester Model # U2A-LQ4B Serial #: UAAM 25574 Supposedly, this engine was used in FarmAll Super A and Super AV series tractors. I have replaced the battery and the ignition coil with a 12v internal resistance model from NAPA. I have disconnected the wiring harness except for battery to solenoid to starter, and battery thru external on/off switch to + side of coil. The – side of coil is connected to distributor and a remote starter is connected to solenoid. Everything else disconnected. In the process of trouble shooting I have replaced points, condenser, rotor, distributor cap, and plug wires. I have a 12 v trouble light connected to the – side of the coil and it flashes as one would expect to show the points are closing (and field collapsing). IF I remove the plugs, ground them, and connect them to the plug wires the following is observed:
The plugs will not fire when the starter is engaged. However, the plugs do fire as the engine continues to rotate (thru inertia) after the starter is disengaged (remote starter button released). Does anyone have any idea what I am doing wrong? Randy Glasnapp
