Hello Minicab family, I have 98 Bravo with 3G83 DOHC engine, and have replaced the original battery with NoCo NLP30 Li-ion. Don’t drive much due to cold weather/winter, but have made sure to keep the battery charged/start it frequently. During the last recharge/start-up, I noticed that the 3 lights (A/T temp, exhaust temp, and battery) stayed on after cold start. I let the engine run for ~5 minutes and the lights did not go out. Is this something that will reset on its own, or will I need to reset them myself? I looked in the manual that came in the glovebox, and will attach the translations here for reference (note under exhaust temp warning light re: battery light, but nothing noted for the A/T temp light). Thanks in advance for any insight!
I'm tempting to blame the NOCO battery, although I have one installed on my newer 4A30 motor without issues. For troubleshooting sake, I'd want to either charge the NOCO with a wall charger OR replace it with a car battery temporarily just to see if there is any change. You mentioned you've been charging it, do you just mean by running the engine? I can't imagine all these lights would be relating to something actually being wrong, especially if it's running and driving OK, but who knows. Start simple.
Thanks for the reply, MikeD! I do have a wall charger for the NOCO, and also a battery tester that shows it reading over 12v on a full charge. I’ve been charging it with the wall charger, not the engine. Yes, it runs and drives fine. I’m just curious if I need to do anything to get the lights to go out, or if they should (eventually) on their own. Thanks again MacJo
What about voltage when the vehicle is running, do you have a way to test for that? It should be 13+ volts. I don't think those lights need time to reset, they should just go off when within the spec. I wonder if your alternator isn't charging / got a bad ground somewhere. Do you have any issues with the vehicle running / battery dying? My AT light is on almost full time but there isn't an issue with my AT temp. But for all three to stay on makes me think it's trying to tell you something.
Reporting back! Was out of town for about a week, came back and started it up and all of the lights are off now. My assumption is that it was battery related, and maybe just took some time to reset. Thanks all for the suggestions! MacJo
