Voltage regulator fried

Everything seemed fine when I parked the TO-35 weeks ago. When I tried to start it yesterday, the voltage regulator fried as well as melted the wire form the regulator to the ignition switch. The regulator is only a few months old :-(
Could a generator gone bad cause this? Any other possibilities or ideas?
Thanks,
RogeR

check your ignition switch, may be worn and shorting. just had to replace mine on my model 20 ind. a few months back. may have to start with a new regulator now also. that way you know what your working with.

Hi Smilie;
Thanks for the reply.
The ignition switch checked out O.K. Thanks for the suggestion.
I'm thinking about converting to an alternator.
See my reply to Bob below.

I have bought a new generator and regulator in the five years since I bought my 2135. I had the Gererator rebuilt by an elderly gentleman who really seemed to know what he was doing. That's why I had him find me the new regulator when the time came. Anyhoo, I can't remember which purchase it was when he told me to do this, but he told me to spark a couple of wires in an incorrect connection. He just wanted me to touch the wires in order to set the polarity. I really don't understand why he wanted me to do that, but I did it and haven't had any problems.

Surely somebody here knows what I'm talking about?

HI Tom;
Thanks for the reply.
Electrical problems can be tricky and downright frustrationg at times.
I don't know about polorizing a generator- thought that was done only with alternators. I, too, am hoping someone will chime in to shed some light on this topic.

You never polarize an alternator, only generator's because they can be either + or- polarity, an alternator can only be - ground. Not all generators have to be flashed (polarized) if my thinking is right, but most do, including both our 165 massey and 1600 oliver. From what I've read, your regulator is probably shot if the wires were fried, and I'd replace both the genny and regulator. You probably do have to polarize it, so make sure you have the proper procedure for your model, as some are different. Instructions should come in the box w/ the regulator on how to do this.

Hi Donovan;
Thanks for the info re: polorizing generators. I'll try to keep it straight in my ever-failing memory :-)
I've pretty much decided to convert to an alternator at this point. Seems that's a more reliable and less expensive way to go.

It kinda depends on the generator. I had the one for my 1600 rebuilt for about $40, but the one for our 165 was a rebuilt one they had in stock for $125 or so, and they had to switch the tach drive from the old to the new one. The regulators are a bit steep at about $40, but when the generator is fresh it will charge just fine. The new one on our 165 puts out enough to charge the battery at 10 amps and keep all 5 lights on which take about 25-30 amps. More than enough, and really quite simple fix. Alternators definatly are nice, don"t get me wrong, but if it came with a genny they really aren"t too bad. I can give you the name and number of the shop around my area that rebuilds electrical components if you want. They may even help out with a conversion.

Hi,
Yes its possible. I don't think there is a problem with the generator (dynamo) as it is designed to put out a high current. I think the problem is more likely to be the voltage regulator which failed and could not cope with the current and something had to go.

Hi David;
Thanks for the reply.
I tried a spare regulator and the same thing started to happen, only this time I was ready for it and immediately turned off the ignition.
Any other thoughts?

Did the battery go dead, or was it removed and replaced, either of which may have affected ground polarity?

I sounds like the polarity of the battery ground did not match the generator's polarity when it was started.

You need to figure out what went on, and repair as needed, then make SURE battery polarity is correct, and then polarize the charging system BEFORE startup.

Hi Bob;
The battery is fine and nothing had been disconnected or reconnected. As I said in my first post, all was well when I parked it a few weeks ago. That's what made it puzzling.
Yesterday, after replacing the burned wires and inspecting all the others, I disconnected the generator and it started right up. I kept a hand on the new wires, feeling for heat and everything seemed fine. I've concluded the generator is bad. I'm considering converting to an alternator.

OOOPPS!

That was my post, not Robert Klein's!
That auto-fill-in feature in the name box is a bit touchy!
