Have a 98 Monaco Diplomat w/Cummins ISB275. Looking for the correct part number for the Alternator.

Most likely a Duvac alternator. Get yours rebuilt or call one of the online alternator places and tell them its duvac.

Non Duvac may not work.

Quality Power comes to mind.

Welcome to iRV2.

There should be a tag on the alternator with the info you need to find a replacement or a rebuilder .

There maybe info from Cummins available if you have the engine serial number .

Recently replaced my alternator. I found the best price at Quality Power High Output Alternators & High Torque Starters I decided to replace my 160 amp Leece Neville with a 200 amp Delco Remy 28SI. The install was fairly simple except on the DR you don't connect the excite wire since it is self exciting. Bought the new onewith a pully and had my old LN rebuilt and carry it as a spare.

That's where I got my replacement alternator. Great guy to deal with!

My alternator crapped out back ~7 years ago, luckily it happened while the rig was parked at home. Pulled and took it to a rebuild shop that does all the rebuilds for large equipment in our area. Done in 24 hours and cost was $185.

Also, recently installed a Bluesea ML-ACR and if my alternator goes out it will keep the chassis batteries charged from the generator. I can easily monitor voltage on my Silverleaf display.

That blue sea is rt up there with a residential fridge for most beneficial upgrades isn't it.

Jim, I'm not familiar with that product. Is that the only function?

Yes the Bluesea is up there at near the top as to upgrades.

Joe, back in May I was starting to have doubts that my Lambert LE415 maintainer was working correctly, my chassis batteries were slowly but surely starting to deplete. If I charged with a small charger they would do fine and hold a charge. I fooled with it for several weeks.

Several other Monaco owners had installed the Bluesea and after doing more research it seemed like a good idea. It actually replaced the Lambert, BIRD, and Isolation Solenoid. It will combine both battery banks if there is a charging source (generator or alternator). I simply removed the isolation solenoid and put the bluesea there. Hardest part was running a wire from the dash to the compartment for the switch.

It works automatically, or you can work it manually. I replaced the auxillary start switch with the Bluesea switch and it serves the same function or I can shut off the Bluesea and/or turn it on. The switch actually has LED lights that tell you when the battery banks are combined.

Here's a thread I did on it, https://www.irv2.com/forums/f115/win...ck-540763.html since then several other members have installed.
