Is this an old golf cart that has a stepped speed controller? Most newer golf cars have s smooth transistor speed controller with fixed current limits. The old stepped controllers didn't have a fixed current limit and to much right foot means to many amps. Some purple brush pig tails and commutator pitting would be a good sign of to much current.
