Had some electrical issues this week. One morning (5:45am) my headlights died during a coast and came back on with the bump start. I quickly changed my SG to show voltage (dropped off engine temps since i leave the grill 100% blocked right now). My voltage was 13.9-14.1 with the engine on. With it off it was at 12V and dropped to 10.0v and the headlights would die. I decided that my alternator was not running long enough to keep the battery charged
or is that a
?
So after work I went two blocks to my local interstate battery location. Bought a charger to hard wire in with the block heater, and I am working on getting a deep cycle battery to add to my reserve capacity. I got a big deep cycle (13" long, 210 min reserve capacity) bit I am having a hard time finding a place for it. its too big for the nose cone and its too big (tall) to fit in the tail under the floor. I have a box for it and could put it in the cargo area but I want it hidden.
I am thinking of getting a smaller battery, any advice on battery's?
Will I hurt anything by charging one battery and having a second hooked up to the system?
Ideas on how to hook up the battery?
best cables to buy?
Can I use old jumper cables and splice/ join them to get the needed length?
By the way I was running a great trip MPG till I had to leave the engine on to keep my lights on
