After checking both power panels with and without the best hot 12 v battery..... I find that the problem for me has been the battery and not the panel......

The old power panel and battery tested at 8.45 volts at the mid range setting and 8.48 in the high end setting...

The new power panel and a new hot 12 V battery tested at 9.60 volts at the mid range setting and 9.64 in the high end setting....

The old power panel and the new hot battery tested as the same as the new power panel... so the old dirty panel is good for now....


BUT... I have a question which I would appreciate some help understanding how the glow plug does not burn out with 9.64 volts... from experience I know that if you plug into the 12 volt connection on the panel accidentially your plug is gone... bright red and gone.... whereas a small glow ignitor that has one battery and checks out around 1.3 +volts will give you a bright red glow... the same as the panel powered putting out 9.6+ but does not burn out the glow plug.... Thanks...
