66 barracuda variable speed wiper question

Hello Everyone,

I asked this question a while back but the thread was lost. I have a 66 Barracuda with wipers that pop the circuit breaker after about 3 revolutions. I since got a copy of the service manual and the electrical schematics. Now when the circuit breaker pops it turns on the reverse lights. This is totally odd. I followed the schematic and other than both getting a B+ signal from the aux terminal on the key... they are separate after they split.

I plan on removing the switch and disconnecting the it hoping to find a contact out of wack inside the switch, with out cutting the harness I cannot see how many amps the wiper motor pulls even though I have the FSM for diagnostics, I believe it is a bear to remove the motor. So I am hoping to avoid that.

Anyone else had this happen? It happens on the variable speed setting or the single speed setting. I can easily check the grounds and the reverse pull back feature of the motor inside the car... I just have not yet. A new switch is over $150.00 new on Ebay.

Thank you in advance.
Joe
