When running by car starter and turn on the fan the Jeep shouts down. Is there a fix for this.

Question

Installed with evo-all and t-harness. Car starter starts fine and stays running. Turn inside fan on and jeep shouts off. Restarts then shouts down again. If started with fan on runs about 2mins then shouts down.

Hi Jay,

 

Was the EVO-ALL installed as a stand alone unit or with a remote starter?

What is the 12 digit service number written on the back of the EVO?

What year is the Jeep Compass?

 

At the moment, it seems like the fan is causing a power drain which may directly affect the tach reading. Both problems you mentionned "Restarts then shouts down again. If started with fan on runs about 2mins then shouts down" normally happen when any unit cannot detect tach a proper tach signal.
