First Official Breakdown! (Help please!), Couldn't have picked a busier intersection Options

[tvdinnerbythepool]

Took my poor girlfriend suffering from a nasty cold out for some fresh air and to pick up dinner. Little did she know she'd get to push a 914 through a busy intersection at rush hour. (IMG:style_emoticons/default/driving.gif)

So here's the deal, the car quit right after I pulled up on the heater handle by the gear shift...well that's odd! Must be a coincidence.

Got the car pushed to a parking lot, it cranked fine but I couldn't hear the fuel pump. So I checked and I blew the 15 amp fuse in the engine fuse box. Swapped out the fuse, problem solved! Fuel pump kicked back on and away we went! (Glad I finally got an "oh shit" bag in the frunk a couple of weeks ago, that's the FORD bag in the pic, don't judge! lol)

When we got home, out of curiosity I pulled the heater handle up again, and son of a gun, it quit. Fuel pump silent, fuse blown!

Can someone tell me to connection between pulling that handle and the fuel pump circuit?? (IMG:style_emoticons/default/hissyfit.gif) (IMG:style_emoticons/default/WTF.gif)

On a more serious note. Electrical work doesn't lend itself to guesswork.

If you don't already have one - get the Haynes manual with wiring diagrams and a Digital Multi-Meter (DMM) at HF. They aren't expensive ($30?).

With those two items you can solve any wiring issue on a 914 with patience and the half-splitting method. This method of troubleshooting electrical problems will save you a ton of time if you apply it with rigor. It is the method taught by USAF technical training. It works and it is the fastest way to find an unknown problem.

If the link above doesn't makes sense to you for whatever reason, Google half-split troubleshooting and find an article that you fully understand and then implement the method. It works. It works even better on complex systems and it works even better when you're under immense pressure to get something fixed fast. In short it works - I've used this method for over 30 years since it was taught to me by USAF in tech school for electronics.
