Hey everybody! Just joined the club yet I've been here many times reading others questions and solutions. I've looked for the question that I'm going to ask and haven't found the exact same problem posted. I have an 89 245 it has over 500,000 on it now and has been my truck(overload coils on the back) for almost 20 years. As long as I've had it it's had this gremlin, I start it, start driving, look at the dash and realize that the speedo, gas gauge and charging system aren't working. Somehow I figured out that by simply turning off and then back on the lights that the above will all start working again!! So I've been doing this for 19 years and it's always worked so why mess with it, well it doesn't work any more. Sometimes when I start it everything is fine yet sometimes not and I haven't been able to drive it because of the non charging. Has anybody else ever heard of or had this problem and figured it out?

Thanks in advance!
