Spiftire grounding point

["Kevin B. Rhodes" <krhodes1@maine.rr.com>]

Hi gang, looking for a little quick advice. Where is the ground point for the
Turn signals, electric instruments and heater blower on a 77 Spitfire?
Operation has become quite intermittent today, all of the above go on and
of at
once so I am assuming it is a ground problem. I would love to know what (and
were) I am looking for before I tear into it tomorrow.

TIA!
