Help With A Jake

Recommended Posts

I need help with my jake. I have a real jake on a 237. I have wired a switch in the cab that goes to the swich on the pump, that goes to the 2 place on the jake. Every time I turn on the switch the 20 amp fuse blows. Any thoughts?

Theres a dead short circuit somewhere between the dash switch & the jakes, or possibly internally in the jake brake. Try disconnecting the wire from 1 jake at a time & turn on the switch, see which one either does or does not blow the fuse, also try disconnecting wires from both jakes & turn on the switch, if the fuse still blows then the problem is in the wiring between the dash & the jakes or in the switch on the pump. If it turns out that 1 jake is shorted internally, pull that valve cover & check for a pinched wire in there between the jake spacer & the jake brake unit, if that checks out then the problem is in the jake unit itself. BTW, a jake brake should also have a switch on the clutch pedal to shut off the jake when the clutch is disengaged.

well as it turns out it is the switch on the pump. That should be an easy fix. The other problem is that it is way out of adjustment. But that should not be that big of a deal either I would think
