12.5 Kohler Gen set Instruments

[akav8r]

I have the 12.5 Perkins/Kohler Gen set. The only "engine" instrument
that works is the Volt meter. Can anyone help with the location of the
sending units on the engine for Water temp and oil pressure. I have
checked the gnd at the instrument panel and got no results, this could
still be the problem. I see several sending units on the engine but am
unsure which ones are tied into the auto shut down and which go to the
instruments. Also if anyone can help with a procedure for testing
either the instruments or the sending units. Any help is greatly
appreciated.

THANKS
