Title: 88 Samurai, Idiot lights stay on
Post by: 88Samy on August 12, 2010, 08:57:57 PM

I had the alternator replaced in my Samy a year ago or so and after that, the "check engine", "battery", and "brake" idiot lights stay on. The battery is charging fine as I've been driving it for months with no issues.  I looked at the electrical schematic and I think it might be a blown diode allowing current to leak back to the idiot lights.  Does anyone know how/where to locate these diodes?  Or, is it something else?  Thanks

There is a good possibility that you have a ground problem with your instrument cluster. I'd suggest pulling it out and following the ground wire to make sure it's connected properly. I would suspect that.
