Failure of 1992-ESP by Ample Power

Postby flyguy on Mon Aug 17, 2009 4:30 pm

My 1992 ESP has failed again. I believe this is the third time. There is no display except for "?". No reponse to keypad inputs.

The failure may have been preceeded by accidentally running batteries way down between July 10 and 20. The last time Ample Power repaired it, it seemed to read normal on Batt bank 2 but give me garbage info on Batt bank No.1. I have 4x 6V 210 Ahr Trojan golf-cart batteries in two 12V banks. I have disconnected and reconnected the two cables to the unit. No guidance whatsoever on failures in manual.

hope you can help please.

One of the parts used in the ESP has been unobtainable for several years, making it non-repairable.

A new monitor is in the works.
