Last night I tried to start my 914 to move it out of the garage...and it didn't start. When I turned the key, the auxiliary fan came on because the lever was pulled back. I turned off the fan, then proceeded to start the engine and it just cranked. I turned off the key, then turned it to the on position. This was when I noticed the fuel pump didn't come on. Why? During my check I discovered the rear fuse of the two on the relay board in the engine compartment was blown. A little research told me that this fuse is for the fuel pump and aux. fan.
So, I disconnected the fuel pump, put in a new fuse and it blew when I turned the key. Another new fuse, reconnected the fuel pump, disconnected the aux. fan, turned the key and the fuse blew again. It's not the fan. What is causing this? I drove the car in there less than two weeks ago!! It's strange that the aux. fan came on the first time I turned the key. Now it won't work with the fuse blown. Somebody please help me. I have to move everything out of this rented garage tomorrow. This includes my 914. I'd rather not have to tow it if that can be avoided. |

Just to make sure, in what condition was the plug to the AAR? The most common problem I have found with those is not an internal short, but rather the plug being uninsulated allowing it to ground against the case, often intermittently. If the plug has bare metal showing try insulating that first.

If the plug has bare metal showing try insulating that first. That's a good question, and I paid attention to that when I was checking everything out. The wire coming out had a rubber sleeve that slid all the way down, protecting it from grounding on the mount. Also, just to be sure, I attached only the left hand bolt, leaving the AAR askew on it's mount. I figured keeping that wire away from the mount while still attaching the AAR would rule out the possibility of the wire touching the mount. Is this what you're talking about, or am I still missing something? |
