Bad Batteries, weird problem

[Tomsu]

I have a 2001 powerstroke with bad batteries. This morning is was about 30F and I forgot to plug in the block heater. So first attempt was a no start. Got out my 6amp battery charger and hooked it up. While I waiting for this slow charger, I thought I would plug in the block heater to warm up the engine a little. Something odd to me happened. When I plugged the heater in, the battery charger amp guage dropped a little. Thought I was seeing things, I unplugged the heater and the needle went back up. I thought the heater was not tied to anything electrical on the truck. So how does it effect the charging of the batteries? Anyone have any ideas?

It effects the charger, because your drawing a lot of current from the house. I would not plug them both in the same plug. That is why your charger needle went down.

The block heater is all on its own.

I did not think of that. They were both plugged into the sam outlet.

Thank you

Thanks Scott and to think that was an experinced reply.

If you have to plug your heater in and a battery charger I strongly suggest to use two different plugs if possible.

All I am going to say is thank god for Circuit breakers in the electrical box at the house.

I guess the smoke coming off the outlet was a good sign too. Can we say plug over load. But I was using a 125amp 12volt charger with start option.
