Zamp Error Code


Recommended Posts

I'm on a long trip and my Zamp Solar Controller has started flashing an error code b01.  The leftmost led below the error code displays a solid red, and the rightmost led is blinking red.  The manual says this error code means the battery is disconnected or less than 3.0V.  The manual also says this combination of leds means that solar power present - no battery connected.  Can anyone tell me what is likely causing these errors?  I have got about a month of traveling ahead of me and I sure would like to figure out what's wrong.  I'm OK right now because I'm staying in campgrounds with AC power, but I have plans to do some boon docking and will need to depend on my solar panels.  I'd be very grateful for any advice.

I've had this happen to me and had to go through a reset. The folks at Zamp are very good in troubleshooting  as I don't remember how they helped get it working.

If yours is a later model with a 40 amp switchable circuit breaker under the streetside bunk access, reset this first and recheck for the error. Beyond this, the next step in troubleshooting would be to trace the wiring looking for a faulty connection at a wire terminal. These can occur at the battery, circuit breaker, or rear of the controller.

Do you have the ability to check the battery voltage at the battery?  If not, you can check the battery voltage on the SeeLeveL tank display by pressing the BATT button.

This turned out to be the problem.  I had a blown 40 amp fuse, and I replaced it with a circuit breaker that I ordered from Amazon.  Fixed the problem and everything is working fine now.  Kudos to Mike at the Oliver service department for correctly diagnosing this problem and suggesting I replace the fuse.

Thank you for closing the loop on your issue.  That information will help someone in the future!
