SteveB Posted March 4, 2022 Share Posted March 4, 2022 Hi Everyone: I’m new to the group and I want to say thank you to all of those here that have contributed to solving problems fellow owners have. For me it has been immensely helpful and I have downloaded and printed a binder of solutions I needed. I have solved many of the coach’s issues, thus retaining my sanity through member’s experience, photos, suggestions and solutions. I purchased from fellow Monacoer,“halwoodsvt”, his 2001 Windsor. Hal kept the coach very well maintained, but there are many items that need to be addressed and the group’s archives has been great source of knowledge. So I have looked through the archives and I cannot find any comments on the second Hamsar relay which on my wiring diagram shows it as a 4 blade 6 volt relay. Which brings me to the following question. There are four relays in my FRB that are wired to relay sockets. Facing the bay there are two on the left and two on the right. There is an empty 5-wire relay socket on the right just below the Hamsar relay. The Hamsar has 5 blades and is currently plugged into the 4-wire socket. I don’t think this is correct and I cannot find any information on the 6-volt Hamsar relay called out in the wiring diagram. Any part numbers would be helpful. Thank you Link to comment Share on other sites More sharing options...
MyronTruex Posted March 4, 2022 Share Posted March 4, 2022 Six volt relay would likely be an alternator fail light relay. I'm sure more help is on the way shortly. Link to comment Share on other sites More sharing options...
SteveB Posted March 4, 2022 Author Share Posted March 4, 2022 Thanks, I will search for a part number Link to comment Share on other sites More sharing options...
jegall Posted March 4, 2022 Share Posted March 4, 2022 I have almost the same panel with one empty relay socket . You can call me at 918-284-6071 all my background is electrical. Link to comment Share on other sites More sharing options...

jacwjames Posted March 4, 2022 Share Posted March 4, 2022 I just went through the same thing with my coach while I was trying to solve a problem. Ultimately I took all the tape off each of the harnesses and looked at the wires, each wire has a label on it indicating what it was for. Through trial and error and using my chassis wiring diagram I was able to identify each of the relays. I will try and take a good picture of what I have, I took the time to label them all to save any future aggravation. Link to comment Share on other sites More sharing options...
Solution jacwjames Posted March 4, 2022 Solution Share Posted March 4, 2022 (edited) Here's a picture of the 4 of the relays that I labeled. The top one is a brake sense relay for the transmission The lower one is the Alt Fail relay The lower right one I labeled DLR which I think is normally used in Canada, this is empty. The fourth is on the left hand side of the panel and already had a label for Driving lights, this normally would connect the high beams and lower driving lights together but I removed the relay and used a jumper wire so now I can have the high beam lights on separate from the lower lights.

SteveB Posted March 5, 2022 Author Share Posted March 5, 2022 Thank you all. I think that perhaps the Hamsar relay is in the wrong socket being that it has 5 blades and is currently in the socket with 4 and 4 wires to it which is perhaps the Alternator fail relay. I think it belongs in the one with 5 wires going to it. (DRL?) I'm not sure, as there is no labeling. I guess Jim I have to remove the plastic cable tubes like you did to find out their function. I don't need DRL but it is a nice function and from what I here necessary in Canada. Thanks for all your help, Steve Link to comment Share on other sites More sharing options...
jacwjames Posted March 5, 2022 Share Posted March 5, 2022 Here is a copy of my chassis wiring diagram, it should be close to your 2001. When you open it and zoom it will be blurry. Ht CTRL5 and it will clear right up. I use the search function to navigate through the schematic to find the location of what I'm searching for. 2002 Windsor Chassis Wiring Diagram.pdf Link to comment Share on other sites More sharing options...
SteveB Posted March 5, 2022 Author Share Posted March 5, 2022 Thanks Jim, could I please have the number/marking on the ALT FAIL relay? The schematics (mine and yours) show 2 Hamsar relays and I have only one and I'm thinking it should be in the socket with the 5 wires. Link to comment Share on other sites More sharing options...

jacwjames Posted March 5, 2022 Share Posted March 5, 2022 Here's a picture of the Alt Fail Relay. If you are having the Alt Fail light come on the first thing to check is the inline fuse back at the alternator. Link to comment Share on other sites More sharing options...

jacwjames Posted March 5, 2022 Share Posted March 5, 2022 (edited) One problem is the original Hamsar 6 volt doesn't seem to be available anymore. I've done multiple searches and came up empty. Here's an older post from RV2 discussing and post #15 shows a relay off Amazon. https://www.irv2.com/forums/f115/alt-fail-hamsar-relay-379921-2.html Edited March 5, 2022 by jacwjames Link to comment Share on other sites More sharing options...
SteveB Posted March 6, 2022 Author Share Posted March 6, 2022 Thanks for the link. I see another member ( Dr4Film) was looking for the same thing in 2013. https://www.irv2.com/forums/f115/need-to-know-hamsar-relay-model-number-183671.html I will order the one shown above if Hamsar isn't making one.
