5 dummy lights?

Driving my svx home this morning, and at a light i noticed i had 5 dummy lights? Steering, battery, brake lamps (or whatever) brake, and ABS.

Immediatley shut her down and checked under the hood... No loose connections, belts are in great shape, and are tight... Ugh, the power steering and brakes both work, was using a bunch of electrical stuff at the time with no problem.... Nobody here to check if my lamps arent working.
Took the negative off for half hour and they're still all on...

Any suggestions?

It's a common problem. It's probably the rectifier in your alternator.

Definitely the alternator!

I had the exact same problem. When idling at night with the lights on (750rpm) the dummy lights would start to glow faintly. If I raised the rpms a little or turned off the lights, they went out. Checking them with a voltmeter, the lights started to glow when the voltage was 11.5V

I replaced the alternator with a new Subaru one and all the problems went away. Idling now with 13.9V.

The dash indicator lights test circuit, incorporates blocking diodes to eliminate a sneak circuit which would otherwise exist. In an event involving faults within the alternator rectifier network, alternating current is induced on line. The result is pulses of reverse voltage, which pass the blocking diodes in the test circuit and energise the indicator lights.

I would rather put in a new alternator than take out those little bulbs behind the dash!
