I know there are a lot of different opinions on original vs modifying. I'm a keep in original kind of guy, or as original as possible. Its 6v and I would like to keep it that way. I haven't had any trouble getting 6v parts. But........ my battery charger went out. I've been looking for a charger like the one I have today (only a working model). Its a Die Hard 2/15/125, 6v/12v, automatic/manual/deep cycle.
I've found a few chargers that say 6v but only on the higher starting amperage, not on the lower charging.
I figured I would have trouble getting 6v parts for the truck, not trouble finding a charger.

 

Here's some options found on a quick google search for '6 volt battery chargers'. Maybe there's something here that will help.

LOL!!
Us Merc guys gotta stick together.

 

Just do what I did. I bought three 6V Optima batteries (one for each vehicle in my signature) from the local Interstate battery dealer. Everytime I feel the battery gets week, I take it into to him to test and charge. He charges it overnight and then I pick it up. If it doesn't take a charge, he replaces it with another Optima. The Optimas have a 3 year warranty and I already had two of them replaced under warranty.

 

That's unbelievable! For a battery that costs $120 or more?!

 

That happened before I had my wiring replaced in the Airflow and before I had the generator rebuilt in the 52 Panel. Both batteries weren't being charged and mainted properly by the electrical system in each vehicle. Usually a cell would go bad. At least that's what they told me.

Now they're all better and haven't had a problem.

 

I'm going to pull my generator off next month and have it looked at. Mine seems to work but I want to have it checked. I know my battery is bad, I was hopping to limp by with it until spring. It would hold a charge for a day or so.
I read somewhere that generators are set based on the speed or RPM of the engine. I need to learn more about this.
