Upgrade golf cart wiring kits. The stock wiring in golf cart applications is #6 gauge,
which is good for about 300 amps. Anything over the 300 amps causes the wires to heat up. When using a
golf cart off road, work environments or using larger speed controller it's best to upgrade #4 gauge wiring to handle the amp flow.
On Club Cars leave factory wire running through obc, Wire runs Battery negative through hole in obc to controller B-.
Add new wire to same connection points just not through obc. Connection will have dual wires.
