have a problem with the electrical (the cluster,and the engine) driving
down the road when all of a sudden lights flicker rpm drops and lights
turn off all of them even the head lights then the engine shuts off when
stopped at a stop sign or stop light. the rpm will drop to about 3000 on
the tach then shut of the engine i am trying to fix this problem for a
friend but i can duplicate it when i am in the truck she and a couple of
her friends says that it happens but it won't work for me so i told her
that the truck is cursed. but need adivise on how to trouble shoot this
one i never heard of this happening with a vechical without an alarm.
What type of truck?
It might be a loose connection in the bulkhead connector. The main feed carries
lots of current, and thermal cycles the hell out of
the pins. You can grab the harness under the hood at the connector and wiggle to
see if you can duplicate the problem.
Something similar happened to me twice. It happened the first time, I came
back the next day and it started up. 3-6 months later (in the middle of a
snow storm) it happened again and the next morning it was still dead. It
would crank, but wouldn't start.
Each time I still had a starter and wipers but I did not have anything else
and it wouldn't start. I traced it to the fusible links from the alternator
to the fuse panel. Cut out the old (corroded/rotted) old ones, put in new
ones from NAPA -- fired right up.
HTH, electrical problems are the worst!
If you take the battery terminals loose and THOROULY
clean them(SCRAPE THEM )and wash all connectors with baking soda and
water.Then rinse them with water and make sure they are securely mounted,
that problem will usually go away.
