Re: 12 V electrical problem
I wanted to thank you all for your help and efforts the past few days. I did locate the problem… a very simple one. About 2 years ago, I had experienced a failed primary engine battery and had to use my dashboard Aux Start switch to start the vehicle. In order to avoid having the drained battery experience repeat itself, I installed a heavy duty marine battery switch (you have probably seen them.. red, round and rated at 300 amps) so the battery could be switched off when I did not plan to use the MH for long periods of time. I did not realize the electrical system was designed to start the engine from the ‘house battery’ without actually depressing the Aux Start switch. Well, you have probably guessed by now, the disconnect switch I installed was in the ‘off’ position…. noticed it when I was looking for any other inline fuses that may have been causing the problem. I had COMPLETELY forgotten about the battery cut off switch. After turning it on, all was well. Talk about a dumb a** thing to do! I guess age is finally getting to me. I thank all of you for your help and I will try to NOT cry wolf in the future. I will say this though, I learned a great deal about my rig I did not know, but more importantly, learned there are good people still out there willing to lend a hand and their knowledge to a complete stranger.633Views0likes0CommentsRe: 12 V electrical problem
Thanks for the suggestions, I will check them in the morning. I am assuming that the "black cubes" I referred to are in fact relays. I'm assuming this provides isolation from the chassis cabling harness. So far I have not seen any specific documentation defining what the various relays control. Good point about probing both ends of the fuses though. No short cuts recommended LOL.340Views0likes0Comments12 V electrical problem
Hello all! I have a 2009 Freedom Vision 3150 DS Class A motorhome. I believe it is the same as a Coachmen Mirada. The chassis is Ford F-53 and the manufacturer was, according to the VIN, Coachmen... However, it is/was "rebranded" by Camping World. To the problem: I was getting ready to make a small trip and when I started her up, the following failed to work: Remote control mirrors, Camera system was dead, Cigarette lighter sockets (accessory outlets) were dead, auxiliary dash fans were dead. Map lights, radio, lights all worked. So far as I can tell, all "house battery" devices are working. There are two fuse boxes to the left of the brake pedal on the drivers side of the firewall. The topmost (and largest one) appears to have power at all fuses and fuses check OK there. The lower fuse box (consisting of 4 banks of 4 fuses) only has power to the lowest bank. The other three banks appear to be dead. The main distribution box accessed from under the front engine cowling seems to have all fuses operational. I say seems because I did not physically remove the fuses to check, but used a continuity probe across the fuses. This may have been a mistake, but man there are a whole butt-load of fuses in this thing! I did not check all the relays cubes as I am not sure if that needs to be don, I'm looking for input from this venerable group of more experienced RVers. Any thoughts or ideas would be greatly appreciated. I really don't want to take it to the shop if I can avoid it. We are retired and income is finite. Thanks in advance to all who may have input or experienced a similar problem.4.1KViews0likes24Comments
