Dolphin / MDS battery charger
 

Does anyone have any experience with these battery chargers?
Mine shows temp light then cycles off and on every 10 seconds or so. When it goes off the temp light turns on.
My assumptions are the charger has a temp sensor on it and either that is bad or the circuit board is bad. I wonder if I can override that?

The chargers that ive seen that have a "temp sensor" use resistance through the charging wires to gauge temp of the battery.....unless you have a separate sensor on the battery then i'd guess yours does the same thing.....in which case it could either be a battery going bad or the circuit inside the charger is faulty....call the company up and see if they can help you narrow things down on the charger....in the mean time i would take the battery to a local shop that can do a load test for you to see the state of the battery
