mini-wini-dan Posted June 5, 2018 Share Posted June 5, 2018 My 87 winnebago has issue with top front running lights. Did not pass inspection today due to this. Mechanic did not find source of the problem yet. Anyone familiar with this kind of problem. He must have checked fuse box. I will start looking myself soon. Any suggestions?

Derek up North Posted June 5, 2018 Share Posted June 5, 2018 Winnebago still has online support, including the wiring diagrams. I think they stop at 1990, but 1987 is probably very similar. 1990 Automotive 085259.pdf 1990 Body 095714.pdf 1990 Body Inst 095715.pdf 1990 Chassis Inst 084682.pdf Quote Link to comment Share on other sites More sharing options...
mini-wini-dan Posted June 5, 2018 Author Share Posted June 5, 2018 I am unfamiliar with wiring diagrams. Is there a fuse box associated with these lights where I would need to check for a blown fuse? Quote Link to comment Share on other sites More sharing options...
Derek up North Posted June 5, 2018 Share Posted June 5, 2018 If all your rear lights are working then there's a problem with the wire that runs from the rear running lights and the front running lights. Or the ground for the front running lights. From the factory (Winnebago) there appears to be no separate fuse. If your mechanic can't understand this wiring diagram, you're paying the wrong guy. 1990 Automotive 085259.pdf Quote Link to comment Share on other sites More sharing options...
mini-wini-dan Posted June 7, 2018 Author Share Posted June 7, 2018 I am the one who does not understand the diagram not my mechanic. Although he seemed uncertain on where to go to fix the problem while charging me $60/hr. That is why I have consulted this forum to see if any of the mini owners have tackled this problem so maybe I can deal with this. I thank you for what you have informed me ablout with the lack of a fuse on this problem which may be evident since the rear lights are working. A bad ground or corrupted wiring somewhere may be the problem? I will do some looking into what I can see by removing lens covers to see what it looks like inside that area. I am open for other suggestions? Quote Link to comment Share on other sites More sharing options...
DanAatTheCape Posted June 11, 2018 Share Posted June 11, 2018 I had the same problem once, I found that when I got up there and wiggled the wires the whole string came on. On mine, and I suspect also on yours, the lights are in series. Also the wires going into and out of each light fixture are tarnished and making poor connections. The wiring diagram helps visualize the path. If you can figure out where the path is "broken", then fiddle with those contacts, you might have success.

akwcanoe Posted August 13, 2020 Share Posted August 13, 2020 This an old thread but still useful. Also I was reluctant to start a new one just for a quick (never is) question. Does anyone have an idea where I might look for the ground for the front upper marker lights on an 83 Sunrader? They were quite dim compared to the rear ones. Ground(s) issues or dirty contacts seemed the place to start. Quote Link to comment Share on other sites More sharing options...
Derek up North Posted August 13, 2020 Share Posted August 13, 2020 The only Sunrader wiring diagram I've ever seen isn't going to help much. 'Dim' is certainly typical of a poor ground. If you can't find the original, there's no harm or danger if you add a new/second one. Quote Link to comment Share on other sites More sharing options...
linda s Posted August 13, 2020 Share Posted August 13, 2020 Sunrader marker lights are all on chain from rear passenger side , around rear to drivers side , up to front and across to passenger side front. Don't think there's a separate ground but there could be damaged wires along the way that aren't supplying full power Linda S Quote Link to comment Share on other sites More sharing options...
akwcanoe Posted August 13, 2020 Share Posted August 13, 2020 Thanks Derek and Linda. Since the rears are good, the front driver's side seems like the place to start. Hoping to minimize tear out. Quote Link to comment Share on other sites More sharing options...
akwcanoe Posted August 13, 2020 Share Posted August 13, 2020 You're right Derek. That diagram is pretty sketchy - especially when I don't have a monitor panel. It pretty much ignores the truck wiring. Regardless, it will be of some use next summer when I plan to tune up the wiring and plumbing in the back. Thanks.

linda s Posted August 14, 2020 Share Posted August 14, 2020 You can get to wires running to the front if you remove the medicine cabinet. Not really a tear out and you can check the voltage from there. Linda S Quote Link to comment Share on other sites More sharing options...
akwcanoe Posted August 14, 2020 Share Posted August 14, 2020 Fantastic!! I would not have thought of that. I really didn't want to start pulling the bases on the lights themselves - unless I have to! I did pop the plug-in light units themselves and it's possi-likely I messed up the contacts. Another cleaning, some conductive grease, and a more careful re-seating might work. But first I will check the voltage. Quote Link to comment Share on other sites More sharing options...
Papademojo Posted September 14, 2023 Share Posted September 14, 2023 Hi everyone, I have a 1990 Mini Win on a Toyota Chassis. How does the camper battery recharge. I assumed it did when plugged into 120 volt. Is this correct or does it recharge from the vehicle alternator or both. Trying to figure this out. Thanks, André Quote Link to comment Share on other sites More sharing options...
Ctgriffi Posted September 14, 2023 Share Posted September 14, 2023 You're right on both accounts, IF everything's still hooked up correctly and components are not kaputt. When on 120V (shore power) your converter/charger unit should juice up a low coach battery—a voltmeter attached to the battery, before and after plugging into shore power, should show you if that's the case pretty quickly. And, like you mentioned, the alternator will also charge the coach battery when the engine's running, if the wiring's still intact and if the isolator unit under the hood (keeps DC power usage in the coach from draining your starting battery) ain't broke. If none of the above is working right, you might wanna start a new thread in this section, Electrical; there are plenty of folks here who can walk you through everything. Welcome to the forum!
