[DeTomaso] Coil wire sparking to a rubber heater hose!

[Mike Drew]

Hi guys,

Lori's Pantera has a new Dan Jones/Dave McLain engine and it runs exceptionally well--above 2000 rpm. But between 1000 and 2000 rpm it stumbles and craps all over itself. Today I decided to troubleshoot it with Garry Choate. I thought it was an ignition issue and I was right. But who would have thought that it would be sparks jumping from the coil wire to a rubber hose!!!!???

Above 2000 rpm the sparks flow through the wire. Below that, they arc to the hose instead, enough so that it killed the motor. 

Re crimping the wire and routing the hoses differently will fix it. 

Who woulda thunk it?
