Hi - hoping others have had similar situations with this generator and can shed some light - I have the onan marquis 7000 in a 1992 pacearrow - went to start this year , it turned over a couple times and since when I hit the start button it just clicks- I get 13.6 volts at the starter solenoid so the power is there to turn it over - thoughts on where to turn - is a bad starter the most likely issue ???

Check your batteries. They could be getting a charge at 13.6Vdc but still fail a load test. Start your coach, hit the "emergency start" switch on the dash and then try to start the gen-set.
If it's not your batts then hit the starter with a hammer and see what happens. Pull the big starter wire and inspect the connection, look for oxidation in the cable. Check the other end too. Could be battery cables as well. Pull starter and load test it.
Hopefully this gives you a few directions to go to get it resolved... good luck.

Check for 12 volts while holding the start button. It should drop to 10 volts, If the starter is engaging.

If it drops to 0 volts, you have a cable connection issue.

Thanks for the feedback - I did load test batteries on they are fine , in fact , all new . When I engage the dash gen button it doesn’t turn gen over nor does the button on the gen - I get 10 volts when I engage the button - all battery connects have been cleaned and are in good condition- going to replace starter and go from there-

Your starter will come out the bottom with generator mounted to RV. If memory serves me correctly, you may have to remove the fuel pump.

Did Onan even make the onan marquis 7000 in 1992 ?

Because replacing the starter on Onans can be difficult and expensive, I 'd try one more thing. Even though it sounds like you've done some decent voltage drop testing. I would take a last shot at cranking the starter directly using jumper cables connected directly to it. And the other end your car, car battery, or instead a jump box if you have one. Just because wire connections can be tricky and you'd hate to find a bad one AFTER putting a new starter on.
