Brand new Model 0058960 S/N 633902 Controller OH6680B.... Upon installation with new charged optima sealed battery.. After 12 hours, "inspect battery" displayed. After two days "Low battery" message displays. Rechargeing the battery from a stand alone charger, resetting.. All is fine for another day then the cycle was repeated. Battery voltage at the battery is 11.4 with generator off. 11.30 when running. Terminal T1 are connected in the switch as well as the generator and 120 volts is present (fuse is good).
Anny suggestions?:confused:

First of all WHY?? Do you just like spending money? I see no real benefit to dropping that battery in that generator.

That being said, I am not 100% sure that you are getting NO charge from your generator. You will need to test that. I am wondering if the charger in your generator is compatible with the battery you are using. If so, one more argument against the battery overkill.

From the voltages you measured at the battery, 11.4 & 11.3, it is obvious the charger circuit is not working. Are you aware that the engine in the generator does not charge the battery even when running? This is unlike a riding mower or automobile.

The charger is usually in the transfer switch and sends a DC voltage to the battery at all times to maintain the battery in a fully charged state. Start your trouble shooting by identifying the charger and measuring the supply voltage to the charger which is usually 240 volts AC. Only do this if you have some electrical skills as you can easily hurt yourself!

I have an earlier model Generac that was nearly destroyed by rust due to two batteries exploding. No I did NOT check the electrolite as I should have.:eek: I switched to a sealed battery to help prevent that happening with the new gen. I got a deal that I couldn't refuse on this battery :D Less than 1/2 price,or I would not have used it. I probably will mount the battery remote if i have to go back to a serviceable battery. Will be a little easier to service and if I screw up again.?.. it won't be such a disaster. There shouldn't be any compatability problems.. I used it for a month on the old unit with no problems.:)

Thanks for your reply:
The two readings just showed me that the generator was using a small amount more current while running than at rest.. And as you said. No charge voltage present. The battery will charge quickly with another charger, so it's not a problem
On this model, the charger is part of the control module (according to the book). So If the 120 volts input from the switch is not there.. the charger will not work. I am going to retrace my steps in checking that line ,since I had to add it when I installed this unit. Can't be a defective controller! It's new. My experience in trouble shooting a problem has taught me to check the last thing I worked on! :eek:

Found the problem...The 120 VAC wire that goes into the small "funky" terminal board was makeing intermittant connection. You must push down on the connector to push the wire in. Then the wire is clamped.. well it was not springing back. I would only be able to read voltage when i pushed the meter probe in beside the wire. As soon as I removed the probe, the wire was loose. Don't know what made it stick in the "unclamped" position. I blew compressed air in place of the wire while I compressed the connector and it worked. maybe some foreign material kept it from clamping down ?

Glad you found the problem. I too have a sealed battery supplied by the Generac Dealer and it is not a problem for the Generac charger.
