Is the 13.8 volts still ok?

If so, then the fault should be fairly straightforward to repair.

Fuzzy Clam-Tnx for suggestion to chck for the 13.5 vdc.- checked with multimeter between pins 5&2 on connector and as with 30v there was approx 2/3 volts after switch on and then dropped to 0. also LED above on/off switch comes on bright first and and then goes dim.
