Need 24v system install help please

[Pfire472]

I am converting an old military 5ton to a tanker. The system is a 24v system with 4 batteries wired in series. How do I put power to my bar and rear lights off of this?

Two ways:

1. You can tap 12V off the series connection between either pair of batteries. In fact, it looks like there already is a 12V tap between the pair of batteries at the top of the pic.

This practice is somewhat discouraged, because putting the load on only one of the batteries causes unbalanced discharge and recharging. If you're only adding a few amps worth of LEDs, it probably won't be a problem.

2. Use a 24V to 12V DC converter.

I second what MtnMan says. You can also Google roscommon equipment center. They have 5 different methods of 24 to 12 swaps they test and reccomend.
