Re: Continued: Bad Diodes

["content22207" <brobertson@xxxx>]

Follow route of electricity on wiring diagram or page M:18:12 of Tech
Manual -- diode is allowing indicator light to ground itself through
any of those downstream devices. Supply is fuse #5, not fuse #12. Door
plunger has no effect. 

Was fuse #12 in place when buzzer went off? Seat belt and door ajar
indicators are tied together. Buzzer box is supplied by seat belt
indicator (as well as headlight circuit). Ordinarily no supply that
way until car energized. But if the diode with red/white wire input
from indicators is bad, electricity can travel backwards from glove
compartment light (live independent of ignition switch), through door
indicator, through seat belt indicator, to buzzer. Two ground switches
for buzzer box: other driver's door plunger and seat belt recepticle.
Simply click the seat belt together and depress plunger to test this
possibility.

You really need to study wiring diagram. Because most DeLo circuits
are live all the time (imfamous "switched grounds" controversy), can
appear to behave randomly. In fact there's usually a perfectly
illogical explanation.
