Hi John.

I don't know which problems youy ar efacing, but here are moe of my
expeirnces with my 480 Turbo. Apparently the Fuel Pump Relay on this model
also controls the A/C unit. The problem I came across was that the relay
does not shut off when I turn the enigine off and takle the keys out, thus
discharges the battery. Out of curiosity I opened the relay and discovered
that it is a quite complex unit. Not only a relay. I noticed that the
contacts on the relay's - and + were dark and that the plastic around them
showed sign ofg high temperatures. I am waiting for a new relay, wherefore I
cannot give you the result of mounting a new relay. Don't know if this
helped you at all. If you know anyone who have encountered the same
problems, please reply.
