FUEL GAUGE CIRCUIT TEST
(1) Remove fuel gauge assembly. Refer to Gauge
Replacement.
(2) Check for c o n t i n u i t y i n t h e w i r e between t h e
fuel t a n k sending u n i t a n d t h e gauge (fuel level i n -
put pin) (Figs. 15 a n d 16).
(3) W i t h t h e i g n i t i o n switch i n t h e O N position,
check for b a t t e r y voltage across t h e B + p i n and t h e
Ground p i n .
