I've been trying to track down an electrical problem with my FI and I've found more problems.
1. When I turn on the ignition switch I blow fuse #9. The Haynes manual says that this fuse powers the turn signals, brake lights and back-up lights. Also, I noticed that the buzzer sounds when I turn on the key, regardless of both doors closed or open. Anyway, I disconnected the brake light switch at the brake pedal, all of the wires to the turn signals and disconnected the back-up light wire at the tranny but the fuse still blows, which then stops the buzzer. 2. No power to the coil. I've replaced the ignition switch with another one, but I'm still not getting any power at the coil. I've checked the continuity between the ignition switch and the coil. I have power to all pin #30s on the relay board in the engine compartment. I have power at the large red wire at the ignition switch. I feel that I'm very close to getting this car running, but with these electrical gremlins I'm extremely frustrated...(IMG:style_emoticons/default/mad.gif) Any suggestions and/or guidance would be greatly appreciated.... -- Rob |

It almost sounds like you might have multiple problems. 904svo's advice sounds pretty good to me. The routing of the power for the coilis really straight forward. from the switch to fuse s9 then back to the relay board. The power does not go through the fuse. It is only a connection point. On the relay board that power should be present on pin 8 of the 14 pin connector, pin 7 of the 12 pin connector and on pin 85 of both the main power and heater blower relays. Take out fuse 9 and work on the coil cct first - it will help keep things a little more simple.
Again to simplify things - take the power lead off the coil while you are doing your trouble shooting |
