Batteries not charging-both engine and coach

[GARY MINKER]

Everyone focuses on voltage voltage voltage. Please use a clamp on Dc ammeter to see if there is a shorted string holding the chargers down at max current or is the "voltage" output of the charger actually low. You need to measure the DC clamped on current in numerous places to determine the charge rates of the strings.

The response from sombody else with same prob had two bad batteries. I have not suspected batteries so far since they are sealed gel type, very expensive($800 for 4) just 2 or 3 yrs ago. I just got all 4 charged in my garage last night with my shop chargers. They all charged to 12.3 + or - a few tenths. By the way they are Optima blue top batteries from Cosco's. I will take them to NAPA today and have them tested, my back already hurt's. Ernie and Chuck, thanks for the offers, I'll let you know....
