The gas tank ground and the turn signal rear left may share the same ground..follow the gas tank ground wire, may be green. You may have to dig in a little farther than just removing the housingI am trying to restore a 1986 samurai.
Everything was working fine, now, when I turn on the ignition the gas gage goes to ULTRA full the left directional ONLY blinks extra fast (the right one works fine) and the Tachometer reads 1,000 and when I rev the engine it maybe gets to 2,000 no matter how high I rev. If I leave the left blinker on for a while it stops all together and I have to shut off the ignition and wait a wile for it to start blinking extra fast again.
I have checked the ground at the left turn signal lamps it's good and the bulbs are good.
I have checked everything I can think of, I have changed the ignition switch and the entire turn signal horn etc setup.
I have run a thick ground wire from the battery very long so I can go to any ground (say the left signal) and ground it to make sure I have a good ground.
I can't find this and I have lost 2 days.
Any Ideas ? Any help much apricated.
