Location: Medford, OR | If/when I ever have an issue with my gigantic LN alt, I will be changing to the standard mopar alt like Lou. 99% of all dodge motorhomes in the 60's and 70's run them. It would be nice to get rid of the idler pulley, AC compressor, and run a standard 440 water pump down the road too. In time..lots of time.... |

| Thanks Lou…and Bill! Lou, your indication that an alternator that's different from the one that's currently installed might mean I'd need different belts has me thinking that I'll shoot for an exact replacement. I've had belt and pulley troubles in the past and carry 3 sets of the correct belts ordered from Jim Black before RVS closed. Remember how Jim used to warn about belts that were the right dimension, but the wrong profile for the pulley? I do miss Jim...
Bill, I'll definitely take your advice and have the truck shop confirm that the alternator is the problem. If it is, I would hope to replace it with a duplicate unit or have the current unit rebuilt.
Any thoughts you might have on my plans would be much appreciated. Best regards! - Grant

Get to the "repair shop", get it fixed, and HIT THE ROAD JACK !
Press ON ! Lou |

| Looking forward to hitting the road…with a charging system that charges and a carburetor that carbs! My friend, the busy Mini Cooper shop owner, was able to source an alternator and voltage regulator for coach 428. If the old one tests okay, I'll have it as a spare. On to the shop! Then on to the road! Best regards - Grant |

| Had a good week of repairs in Portland, Oregon last week. As Bill suggested, the alternator proved not to be the source of our charging problem. The alternator wasn't receiving voltage from the ignition switch. Two "parasitic shorts" we're also discovered and fixed. I was impressed with the service of Automotive Battery and Electrical (ABE) in Clackamas, Oregon.
May also have found a good shop to work on non-electrical issues...S&T Truck Repairs...which is just across the highway from ABE. They installed the thermoquad replacement Lou recommended (Thank you, Lou!), and the coach started and ran smoothly for the first time in a long time. I'll be taking it back to S&T next week to analyze and deal with an exhaust leak
I took 428 into S&T Truck Repair late in the day. The shop mgr had gone home. It was received by one of two remaining young mechanics. Within 5 minutes, they were both under the coach. "Look at this suspension, Justin!" "Wow! Never seen anything like this..."
Looking forward to having the coach in top shape. Thanks again, everyone! Grant

Location: Lavallette, NJ 08735 | Just a follow up: Everything was hooked up properly, but in 5 minutes, at no charge, a local mechanic pointed out no PCV valve. I bought one for like $3., installed in-line, and #75 was running 10 times better; and I was able to adjust mixture (no adjustment seemed to make a difference, prior). A quick timing adjustment, and HOLY COW! IT WORKS! I can actually accelerate up inclined grades! Now to get to those brake boosters, so as I can stop.... |

DO NOT BUY POWERMASTER 8-47529 or 8-57529 ALTENATOR for your FMC ! The Powermaster Catalog and every sellers listing from it LEAVES OUT THAT IT ONLY FITS A SMALLBLOCK MOPAR ENGINE !
THE ATTACHMENT TAB FOR THE ALTERNATOR OUTPUT STICKS OUT TOO CLOSE TO THE CYLINDER HEAD. Also the Mount Bracket (Reference Link) will NOT FIT either. I bought both of these items and tried to make them work, but they will NOT. Discussions with Powermaster "revealed" the fact that this alternator ONLY FITS a smallblock Mopar which was "missing" from their Catalog and On-Line detail. My apology to all. Lou #120 |
