Re: dead battery on 115 C

Recommend installing a battery cut-off switch. These pre-war cars with their batteries under the front seat pose a challenge on where to mount the switch. Generally, it is preferred to switch the ground side of the battery. I mounted a switch on the steering column about midway between the box and cowl wall. I used the cable from the battery to the starter solenoid to connect to one end of the switch and then had a shorter cable made-up to go from the switch to the solenoid. It was easy to get to and served the purpose well. This mounting worked well for safety, but not good for security. Later, I moved the battery to the engine compartment and used a different kind of switch. Here are some photos. The first shows the mock up of the switch and brackets on a piece of exhaust tubing, the second is it installed, and the third is the Optima battery mounted on the cowl wall. JWL

Later that day. Owen's suggestion is a good one, but the 115Cs do not have a seat riser like the senior cars. Here is a photo with a conventional battery in the tray I mounted in the engine compartment. I used a heavy duty battery post cable disconnect. Got it from NAPA. Not to be confused with the green knob disconnects that are too light for 6-volt systems.
