My 2016 Greyhawk 29MV 12 volt system is acting up.
My leveling system is chirping and the lights on it are flashing on and off
This is with my master switch for the coach either on or off
As I try to start my generator with the master switch for the coach on, it acts like the battery is dead. I.E. it clicks rather than turning over the generator to start it.
I use two 6 volt batteries to get my 12 volts and have had it that way for 3 1/2 years now.
My batteries are 3 1/2 years old so I replaced them with two fresh Interstate 6 volt batteries thinking the old ones went bad.
Same problem.
I always keep them charged up with a solar charger.
That is as far as I have gotten to this point.
Does anyone have access to a 12 volt wiring diagram for my rig??
I have not checked the other 12 volt appliances yet. I will.
I recently was tracing some wiring in my 2017 Greyhawk and came across a loose ground connection on my generator. The frame connection was somewhat loose. After tightening, my generator started much better than previously. Before the loose ground was found, the generator would start but the initial spin of it would hesitate a bit.
Without using a voltmeter you are just shotgunning the repair. This refers to randomly replacing parts until it is fixed. It is better to find out what the problem actually is.
If the problem persists after you have made sure all battery connections are tight, measure across the battery while you crank the generator. It should only dip a volt or 2 initially.
If the battery voltage is solid, the next step would be to check the cable connections at the generator. They need to be clean and tight. If all appears good, take a voltage reading of the 12 volt supply inside the generator.
I have attached the wiring diagram from my unit. It should be fairly close since mine is only 1 year newer.

Thank you for your reply.
I haven't really gotten into it yet.
I will get to it in the next couple of days.
Batteries are new and fully charged.
I'll start with the grounds and wires near the disconnect solenoid and go from there.
BTW I'm an ATP civilian only with a bit over 7000 hours. CFI etc. as well.
FYI I found the problem today. Bad jumper wire between my two 6 volt batteries giving me low voltage situation.
When I checked items for 12 volts it showed correct, but once I put a load on it I.E. move a slide or exercise the hydraulic jacks the system would crash, lights dim, leveling system control panel would beep and more
one of the connectors for the jumper wire was corroded and beginning to show signs of deterioration.
To answer you question as to obtaining wiring diagrams for you Jayco, send them an email witch includes your make/model/year and VIN number. They usually respond within a working day or two with water they have available, for free.
Google search "Jayco" to get their website, which will have the email address to request the wiring schematics. Or someone else may know the email address and respond.
Quick question,
Just getting ready to go on a short trip and noticed that my chassis battery is dead. I can hit the Jump button and the motor home will start. Is there a fuse I am missing, shouldn't the battery charge when it is plugged in?
Thank you in advance

No. The Class "C'"s did not come with that feature only the SENECA'S.

Whoa Nelly!
I was distinctly told, on this forum, that when plugged into shore power, both the chassis and house battery are maintained charge. Is that not true?

Correct, that is not true. First thing I did when we got our Greyhawk was to replace that solenoid with a Combiner 200. It connects the batteries together when either is on charge instead of only when the chassis battery is on charge. It also monitors alternator load and cycles off if needed to allow cooling time.
I highly recommend getting the lithium version just in case you ever upgrade in the future. It will work fine on an all lead-acid setup, the only downside is a full charge cycle would take 5 to 10% longer and this is rare, the main purpose is maintenance.
I make no income from Combiner sales, I sold the company a few years ago but I invented the Combiner over 30 years ago
