Re: Electric problem on 5000. Help needed ...
I think I know what the problem is...
On turbo engines, there is a temp sensor near the fuel injectors that turns on
the little air blower. This is the fan that cools the injectors to prevent
vapor lock. The temp sensor activates a relay which applies power to the
blower motor. This whole circuit is not switched by the ignition switch. THat
is, it can activate at any time. It the temp sensor goes bad, the blower runs
alot and kills the battery. This happened to me and was a real pain to find. I
ended up buying a new battery for nothing. As a temporary move (until summer),
just disconnect the temp sensor wires. The sensor is mounted near the fuel
injector closest to the firewall. Also near the cold start injector. It sits
on a little metal pedestal.
Good luck,
...bill
