WD21daily Posted September 18, 2017 Share Posted September 18, 2017 so my 89WD21 has been acting up lately, first of all my battery warning light and E-Brake light stay on all the time. Well this friday my E-Brake light went off, so i thought oh good one less problem to worry about.... WRONG. about a mile down the road the truck just died out of nowhere while i was driving, it cranked just fine when i went to start it agin but would only start if i used the interlock switch and would die out again as soon as i tried to get on the gas. so i left the truck sit for an hour and came back to it.... ran fine. this same thing happened to me 4 or 5 times since friday, if the E-Brake light stays out for over a minute or two then the truck will shut down and wont move again for another hour or so, sometimes it happens when the vehicle is warm sometimes it happens when its cold. if you have any information at all please let me know, im at at total loss. Thank you! Link to comment Share on other sites More sharing options...
Saturn Posted September 19, 2017 Share Posted September 19, 2017 I'm an R50 guy, but recently my brake and batterly lights came on, turns out this is sort of a code in a lot of japanese vehicles to warn of a failing alternator. I replaced mine, haven't had the lights since. But my truck never shut off or wouldn't start. But those two lights usually means you have a charging system issue, have a shop or parts store run a starting system check on it Link to comment Share on other sites More sharing options...
adamzan Posted September 19, 2017 Share Posted September 19, 2017 Those lights are the code for a bad alternator. If you had an automatic the trans temp light would light up as well. Link to comment Share on other sites More sharing options...
WD21daily Posted September 20, 2017 Author Share Posted September 20, 2017 the alternator checks out good, do you think it could be a weak wire leading to the alternator? Link to comment Share on other sites More sharing options...
Cuong Nguyen Posted September 21, 2017 Share Posted September 21, 2017 (edited) the alternator checks out good, do you think it could be a weak wire leading to the alternator?How was this tested or confirmed? Did you make sure your battery connections were secure and clean? No loose connections?

RAWags44 Posted October 16, 2017 Share Posted October 16, 2017 I had this happen as well. Turned out the tension bolt on the alternator had sheered off. It was just loose enough to cause all kinds of gremlins including the lights on the dash. Link to comment Share on other sites More sharing options...
