A friend purchased a 49 3/4 ton. It had an 8v battery in it and it was removed without identifying the terminals. A new 6v was installed neg gnd. The truck failed to start and the cable (12v type) from the battery to stomp switch melted. A new 6v type cable was put on and the starter smoked. I was not there to witness this, just trying to help. The P. O. claimed it was a Pos gnd system, whitch seems odd to me. I looked at the way the ignition is set up and its the same as my 54s (neg gnd)
The old 8V is gone, but I looked a a pic of it prior to removal. With the terminals toward you the starter cable was on the right. Other 8v batteries I looked at have the Pos terminal on the right . Maybe to be run in a series for golf carts ect. Most other batteries have the Pos terminal on the Left when closest to you.
What can I do to determine if it in fact is a pos gnd or a neg gnd set up?
