Not recommending this for your situation just food for thought.

Iím a huge fan of internally regulated alternators. I hate external regulators and the associated wires.

They even come in one wire systems:

One wire to the battery. Thatís it. Perfect for tractors, classic cars or in this case my wood chipper.

I love getting ride of wires and boxes with better technology.

My diesel doesnít have an engine mounted vacuum pump. Just an electric one mounted up front. Itís only purpose is to run the POS dash air system. I want to replace the vacuum actuators and water valve with electric ones and loose the whole vacuum system. Probably look for a heater/ac controller just like in my Cummins powered Ram 2500.

Like Kota when possible I prefer internally regulated alternators however single wire alternators are not necessarily the best choice for our motorhomes. While they are good for certain applications like tractors and such they are not great at regulating battery voltage.

The "sense" wire from the regulator is usually connected to a spot in the wiring harness where the electrical system supplies the bulk of the voltage to various devices. Typically the "sense" wire would be connected close to where the fuse block is located. This location tells the alternator what the "system" voltage is and in this way the alternator knows when to increase or decrease it's voltage output.

This helps keep the batteries at their peak voltage.

The single wire alternator basically connects the "sense" wire to the alternator output connection right at the alternator which means the alternator doesn't really know what the actual system voltage is.

For tractors this isn't an issue, for vehicles with sensitive electronic equipment it can make a difference.

Food for thought

All true! Didnít mean to imply that the one wire alternators are appropriate for all applications. My 95 360 has an internally regulated alternator with a sense wire connected to the isolator which only returns the voltage that the alternator is supplying to the isolator, not any specific batterie(s).

But that brings to light another problem. What bank of batteries are you sensing the voltage from to control the output of the alternator? If the coach batterie(s) are flat and the engine batterie(s) are fully charged, what voltage is the alternator going to put out? They seem to have compromised and the voltage on the dash just sits at a system voltage of 14 volts, regardless of the state of charge of the batteries, which is what a one wire alternator puts out. Not optimum for battery performance but good for everything else on the system.

Yup....went to a 200 amp power master single wire G3 Ford system.....works great so far. Incidental, even with an externally regulated alternator, the sense wire would still be coming from the same place as an internally regulated alternator......I agree with Dave on this one. Regards, Bob

If that's cheap alternators so be it

Well Rob I guess it just comes down to the idea that us guys with oil burners would rather drive them then work on them.

Huh, I wonder how many diesels make it out to rally's verus gassers?

So you would rather not work on them then drive them?
Does that imply you're afraid to drive them after you work on them?
Check your grammar

No. My old oil burner is pushing 190,000 miles. As a matter of fact we camped at the Dosewallup River last week. You can see a couple of pics here: http://www.airforums.com/forums/f42/...ml#post2162600 Look at post 2145. Last month we were at Silver Falls in Oregon. Just about everything that gets done on the coach I do. Before the Silver Falls trip I mounted 4 new tires on the back after I polished the 2 aluminum wheels. It takes me a little longer than it used too but I got it done. The wife washed the bedding and towels and took them out to the coach this afternoon. The only thing needed for the next trip is to fire up the fridge and fill it with beer and chow.

In my opinion the gas engines in motorhomes are overtaxed for the application. Reflected by the fuel consumption, rpms, lifespan of these 454s. The diesels have their issues too. But given good maintenance and operating practices, the diesel will run circles around the gasser in performance, fuel consumption, and reliability.

We bought the 360 with 64k on it and itís about to turn 100k. Over 30k trouble free miles. We donít hesitate to head out on trips to either coast or across any mountain pass. Itís been from Seattle to Bar Harbor and border to border in the Rockies. It just sings along at 70 on the interstate with the jeep in tow getting over 10 mpg. 13 in nice conditions without the toad.

Nancy and Richard see almost identical numbers. They have done more long trips in their 360 that anyone I know.

Iíll stick with my ďoil burner(s)Ē... Click image for larger version

Good grief guys, I was never serious!
Next time my 454 gives out I'll probably go diesel too

Be careful when discussing diesel vs Gas with this group unless you get more gasser
guys to attend a gathering
Also make sure when you be sittin at the campfire talkin + /- of various MHs particularly diesel vs gas that no one is packin his 45 or has finished his bottle of scotch
Find some more gasser guys to give you support at the next gathering of the MH flock

If I own a diesel, AND a gasser.....do I sit by myself, or alternate between campfires? Get it, "alternate"; you guys were dicussing alternators........I swear the doc pulled my funny bone.

You can own a gasser Tony, you are just not allowed to drive it until you convert it to diesel.
