1975 barth 454 gas burner. Has two batteries for generator, just bought two new ones and gen won't even try to start, no click-nothing. Took ground cable off and cleaned it and it sparked when I put it back on.

To begin with, new batteries should be charged fully before using. Then tested. Many battery companies use the customer as their quality control department.

There are a lot of ways of approaching this.

Lets simplify. Take a known good 12 volt battery and connect it to the genset with jumper cables. Neg to generator ground and pos to the heavy terminal on the genset where the battery cable connects. Start the generator from the panel there. If the generator starts, then we know it is good, and the problem is in the coach wiring or batteries.

How did you get it started?

What generator do you have?

Which fuse blows?

Mary, I have no Generac experience.

Hopefully others can help. I know a few here have Generacs.

You can download the owner's manual straight from Generac's website for free. It sounds like you have a dead short or grounded positive line to the starter. Pull the cover on the front where the starter cable enters and look for a possible arc to ground. Is the cable chafed? If you find chafing, get some heat shrink tubing and repair the cable end. There is a cable running from the starter solenoid to the engine mounted starter through a metal engine shroud. Check the routing of that cable and look for chafing where it enters the shroud.
Good luck

The generator ran when I got the Barth about a month ago. Ed, I will check the things you mentioned sometime this weekend.
Once again thanks for the help and will keep you advised.

Welcome to the forums!

The generator (genset) usually operates from the house battery.

Please tell us more aboout your coach, because locations vary based on year and model.

It is likely that you have two batteries close together. One will be your starting battery, the other the coach battery. The starting battery should be a standard automotive battery. The coach battery should be a deep cycle battery. More often, the coach battery is a dual purpose marine/RV battery. This is not as good as a true deep cycle or trolling battery, but is better than a standard automotive battery. If the coach battery is a standard automotive battery, it will not last very long if you camp without electrical hook ups. If you camp with electrical hook ups, a decent standard automotive battery will not be too bad, since discharge will be minimal.

I would not replace a battery until it is fully charged and tested.

Do you own a battery charger and a hydrometer?
