Anyone know the part number and where I can get an external voltage regulator for my Indian? It is the 73 M300 chassis I believe.

Thanks,

Steve

Anywhere!

All the voltage regulators are the same for any Chrysler V8 from 1970-1987. A few 1968 and 1969 models also had them. If by chance, you have the older thermal strip regulator, I would consider replacing the alternator and regulator with the newer style, you'll have far less trouble.

A Wells (AutoZone, Advance, PepBoys etc.) VR733, total cost is about $14.99.
You can get Mopar performance regulators for around $25, but you're paying for nothing but an emblem. There's only $3 worth of electronic parts in one, but they're potted so you can't repair them.

It's a normally stocked item everywhere. Since the circuit is pretty simple, these regulators are usually not the culprit. It looks like this:

It's located in one of 3 places:

On a Class A small block,  on the metal mount on the top of the transmission
On a Class A Big Block, near the frame rail and starter solenoid on the left side.
On a Class C (Van) Chassis, underhood on the firewall near the battery or wiper motor.

(if I missed a location, I'm not perfect!)

Also, here's a great link for info on the charging system:

Tom,

I found it from a local auto parts store for just over $12 with tax. Mine was located at the back of the engine compartment mounted not on the engine, but on the coach right up front with easy access. Looking at its location, I wouldn't think it would get real hot.

We will see if it takes care of the problem. The mechanic said it wasn't getting the voltage to the alternator to charge the battery. It still could be a cable. I'll update the other thread when I find out if it works.

Thanks for the response.

Steve

If you happen to go to AutoZone, DO NOT say anything like "rv" nor "motorhome" nor "Winnebago."  You'll just get a bunch of guys shaing their heads.  Tell them, in this order:

'73 Dodge
MB300
440

THAT they can find.

Just a quick note from experience:  Unless your alternator is relatively new, if you have to replace the voltage regulator, then you might as well go ahead and replace the alternator...they work together as a unit, and if you replace one and not the other, they will fry each other...not sure why old voltage regulators and old alternators retain a memory of each other, but they do...they will fail if not replaced together.  New alternators for newer vehicles have the voltage regulator built in for just this reason.

I replaced my alternator in 2001, since I had the radiator out, and it was now easy to reach. Along with the rebuilt alt. I installed a new ground wire from the alternator case to the frame. The output wire from the alternator got a new connector soldered on it - the old connection was well corroded.
A little later I installed a new ground wire from the frame to the engine - but instead of bolting it where the old one was, at the rear corner of the tranny, I used one of the bolts that holds the starter.
I havent had troubles with the voltage regulator and the alternator disagreeing, but I go along with knowing how old all of the parts on your motor home are. I will replace my voltage regulator the first time it gives me trouble, as I carry a spare one with me. I will replace my alternator -again- the next time I have the radiator out, which will be in 2010 or 2011.
