    12V Switch Box Relay Electrical Issue

    Thanks for explaining the schematics for the relays. It would be good to get an electrical schematic for the A1. Replaced the entire 3106 circuit ( automatic battery disconnect) yesterday with the update version and the LMTV is now fully functioning.

    12V Switch Box Relay Electrical Issue

    Yes that makes sense. Ordered the updated version of this entire 3106 Link to relay Which looks totally different from mine.. but that is good thing. There are two positives coming into the 3106 per other PDF I posted, one is voltage regulator and the other one is some kind of cutoff, not...

    12V Switch Box Relay Electrical Issue

    Let me get this right, since its important for me to know how it supposed to work. 1. closed / aka closed circuit , the current is flowing, 2. open circuit = current is not flowing. Are you saying if there is NO Voltage on X1 and X2 control terminals than the circuit is open hence nothing is...

    12V Switch Box Relay Electrical Issue

    The relays in question are the 30.313.12.901 I want to make sure they are really the source of this issue.. and defective. Almost considering dump this complexity and just have a proper bypass, which is not easy to do since the wires are huge.. what gage should I be using? or well maybe just a...

    12V Switch Box Relay Electrical Issue

    I have bypassed the 12V selenoid/relay with the a wire and it worked ok in terms of getting correct reading in the cab etc.. ( so definitely the issue is the relay or what is controlling the relay in the battery switch box) I was looking at this a bit longer and there are four white wires that...

    12V Switch Box Relay Electrical Issue

    I did clean up the terminals on the outside off the relay and connector wires, is that what you mean? Is there a way to disassemble this relay and fix it? I did find one for $350 on eBay... crazy, so alternatives would be good.

    12V Switch Box Relay Electrical Issue

    I have developed a strange electrical issue on my 1078 A1. The vehicle was running like a charm, than I turned off the power disconnect next to battery. After a while turned it back on.. The LEDs were acting funny.. but the truck started,, once it started , all was good. Than got home, turned...

    Thanks, I think at this moment I take the best radiator reasonably priced I can get, since seems like the new or NOS ones are not available. I did try to reach via message to fuzzy toaster..,

    LMTV Coolant Leak Diagnosis Suggestions

    Apparently it turns out the radiator shop tried to repair my radiator and sealed the 10 inch crack in the base, but that did not help the result. The quote for proper fix was over 2.6 where they would replace the core.. Hence I am looking ideally for a new radiator. Any ideas where to source...

    LMTV Coolant Leak Diagnosis Suggestions

    Good point; its a large shop dedicated for the big rigs only and they confirmed what I have detected. They always treated me well and respected the fact that this is a hobby . Depends on estimate, but very likely will be doing the work myself. Their thinking is in case the radiator is not...
