Alt Fault flashing and solenoid clicking
Shortly after starting my WB I get a Alt fault, the person I
purchased from said it has always done this. However, just in the last week I get the fault and relays 9 and 9A in the lower distribution panel which are the ALT1 and ALT2 selection relays start clicking. Also a relay, which I am not sure what it is for which is located in the engine compartment mounted on the curb side at the firewall where all the shunts are located starts clicking as well. This relay in the engine compartment looks like a starter relay, it appears to be a large high power relay. In my troubleshooting, I disconnected both relay 9 and 9A at the forward lower distro panel and the rear relay continues to click. Has anyone seen this issue? Is it an alternator issue, a relay issue, or just a ground issue? I see one alternator in my coach, most seem to call the this lower. It is mounted under the A/C compressor. I have seen statements about the other one being below the bed. Is this at rear of the engine compartment, or the front? How do I get to it, meaning, what do I need to do in the bedroom to get to it? My Service Parts list in the blue box shows Delco #1117920 (160 AMP) alternator installed, but not how many. Michael Brundridge 1992 WB40 Georgetown, TX |

have you ever checked the batteries for a ground short? or bad one? I
am not up on it but the first thing I would do is to start at the storage end GregoryO'Connor 94ptRomolandCa --- In WanderlodgeForum@yahoogroups.com, "mbrund" <mbrund@...> wrote: > > Shortly after starting my WB I get a Alt fault, the person I > purchased from said it has always done this.

No I have not. But that is simple enough, just need to pull all the
postive cables off and verify each battery voltage to see if I have some dead cells. I believe all the batteries in the coach require replacement as it is. I can start the 8V92 with just the 3 main engine batteries on a good day. If the engine is hot, I will have to engage the ALT batteries to get it crank over fast enough to start. So that tells me they are not holding a full charge anymore.

Mike you can also encourage a flashing alt situation and then shut
off one bank at a time ?? there are two switches in my louvered compartment near your clicking solonoid for that purpose. A start on weak batteries playes havoc on the starter motor. Many have also proven computer problems start with batteries GregoryO'Connor 94ptRomolandCa --- In WanderlodgeForum@yahoogroups.com, "mbrund" <mbrund@...> wrote: > > No I have not.
