No Power To Dash On RV

by Jason
(Maryland)

Question: We are trying to prep our RV to go on a trip. I reconnected the battery in the cab and am not getting any power to the dash of our 2001 Tioga Arrow. When i do the 2nd start switch, the vehicle will start with the backup batteries. What am i missing? The battery under the hood for the engine is good.




Robbie: If the engine starting battery is dead this could explain the problem (The battery may have been good when you disconnected but is it charged now?). If your battery is good you may have a battery disconnect problem. The battery must be above 10.75 volts for the relay to connect. Using the boost switch start the engine, let the engine run for a few minutes and try the disconnect switch.
If you don't have a disconnect switch make sure you have a good clean ground and trace the 12V from the engine battery and see where it stops.
I hope these idea's help solve your problem.

Thanks for the Question Good Luck,
Robbie
