    JLG 60HA Unable to use any controls from Platform plus engine dies

    No, there were no diodes inside of the foot switch. Just a couple of single pole double throw switches that operate in unison. The normally closed contact on one of the switches had 12 volts on it from the common terminal. The switch was not opening when the foot switch was pressed so that...

    I found the problem. It was a faulty switch inside the foot pedal. I temporarily installed a regular household three-way switch and the controls are back working.

    There is a mistake on my previous post. Voltage reading on on the circuit breaker is accurate but the current is wrong. I was actually measuring current on one of the circuits that is fed by the circuit breaker and not the wire delivering power to the circuit breaker. Upon further investigation...

    I just checked the voltage in the basket. The voltage is 11.78 on the circuit breaker inside of the wiring box. There is approximately .6A of current flow on the wire delivering powering to the circuit breaker. When I push the pedal down the voltage immediately dropped to 1.6 volts and current...

    I have a JLG 60HA. I haven't used it in a while, approx. one year. It worked fine when I last used it. It is a 2WD with Ford industrial engine. PQ controllers. The lift operates just fine from the ground. When I move the switch to platform, the engine slows to idle, the blue light on the...
