1996 engine codes and wiring a battery selector
I'm looking for a diagnostic list of engine codes for my '96 t444e. We're on the road for our honeymoon, got a Scan gauge and it's showing 252 and 164, but if I could have an entire list on hand that would be extremely helpful.
Also we have a solar battery bank on board and I would like to wire in a battery selector to charge these batteries when desired from the bus alternator. I've got the selector but am confused as to the best way to wire it. I know the general concept is to divert the main positive output from the alt to the selector, but I see 2 large wires coming off what I believe is the output charge stud. I have yet to chase these with a continuity meter but was thinking of pulling them both then running a new wire to the selector, and then one back to these 2 wires. (2 gauge or higher) But since I'm not sure what they are or where they go... thought I'd check in here first. Not sure if I divert power away from these both for a short while to charge the house battery if that may be a prob. The second wire looks like it goes into the cab, up near the heater can... A wiring diagram for this engine and chassis would be helpful, been looking with little success.
She's still running a bit hot, but with the scan gauge we can keep a closer eye on actual temps and know when to pull over to let it cool off 👍🏻
Thanks for whatever info or advice you can lend!
