To me (no mechanic), it sounds as if the ohms on the sending unit is too= =20 low, Ollie. I'm wondering if you could get a capacitor or resister to raise= =20 the ohm rating if it was installed at the gauge. And another thought, does= =20 the ohm rating change if you run a different voltage than was intended. Jus= t=20 some thoughts.

Gary H made a post regarding the ground strap. I looked in my shop manual=

no info. I never had one on MS Cruiser. Now it has been explained better.=
