I found this page for PGM 3 repair. It is in Japanese, I tried to auto translate and you can probably figure it all out if you're patient. Now, if someone could properly translate it, that would be much better. Basically it shows you how to repair the PGM3 if you fried it because your valves were sticking. Here's the link:

hey pitty there arent more site telling us how to repair the electronics on these bikes. are thos transistors the only thing that goes on the pgm when it goes like that?

I'm in process of repairing my pgm 3. Only one of the four transistors burned on mine. There are two different sets of transistors. I think the part number is 2SA1385-Z and 2SK1059-Z. The part that burned on mine is 2SA1385-Z. The part is on back order so I can't test it out yet. But I was going to do the same way that link showed. Cut the legs and solder it to it. Looks like that's the only way to do it. We'll see when I get the part.

And this is easy to understand, around the sea urchin everything the picture which is excavated. (As for truth with just the right OK.) With respect to the picture right (the inner part) the transistor burning with overcurrent, it recognized is that the hole opens? Actually you think that you understand that you make see, but black) when the transistor directly receives the damage it is the majority two green color of the right side (with year system. Speaking conversely, at the time of servo trouble here should have been exchanged, is. By the way the transistor above the RC valve to "LOW -> on the side which is moved HI", direction under to "HI -> is the side which is moved LOW". In other words the RC valve does not move the ま of LOW is the ま, don't you think?, direction above is the 逝 っ ちゃ っ て る is? (^ - ^ As for this picture perfection OUT! It understands that it has burnt, but there is also the breakdown which with appearance does not understand normally, so is. When other than PGM you cannot think, temporarily, don't you think? this should have been exchanged meaning is. That front two is black, it will do quietly being there is no relationship.

That was according to my translator!

Hi and LOW relationships with sea urchins. I thought we were talking PGMs, not sea creatures!

can we have that in english ?i know of someone who has repaired one and had no other problems with it.

That was English Wayne!!

I'm working on it!

what does it all mean?is it me or does japaneese not translate well in to english?

What I need is a picture of the circuit borad around the transistors. The fried one I was sent has burned out the circuit tracks too. Anyone help?

What is the status now, can they be repaired ?

So long as it's just the transistors. If the board is toast like the one I was sent, then there's not much I can do...

I have a small collection of u/s p.g.m.'s if you want something to play with. One has no powervalves functioning and the other two have powervalves but no spark???

It sounds good repairing the pgm3...

I have one on my bike which works but doesn't move the valves and i'm waiting one

from a japan market which hopefully will be fine ...

But if it doesnt then,

HELP!!!

RC valve transistors are quite easy to replace, it just takes a while to carefully remove all the potting. I've got a couple of the transistors left over, but I'm not fixing any more PGMIII's just in case my super chipped F3 PGMII blows it's cookies.

I had to order the parts and they took a couple of months to come, but come they did and a PGMIII with dead valves was fixed. Yep, I was pretty chuffed.

If there's no spark fro the PGM then you'll probably find that one of the big caps has blown and oozed it's goo all over the place. I tried replacing one of these too. It took ages to remove the blown cap and then remove another (undamaged) cap from another blown PGM, and then solder it onto the legs of the first PGM. Fiered up the bike and it worked for about 2 seconds. Then sparks flew and the cap exploded. At that point both Paul and I jumped for cover and decided that we'd best put that in the bin. I've since tried again on another blown cap, but with the same results, so it wasn't the cap blown on it's own, but something else causing the problem.

Did you check polarity before installing ?
Electrolytic capacitors have + and - pins and will blow up when reversed.

That could explain why the replacement went pop (unlikely though, as it would probably have (a) not worked off the bat, and (b) I doubt Matt would've installed it incorrectly), but it would definitely NOT explain why the original Honda factory item died.

It stands to reason that if the factory component failed, and then a replacement component failed, that the fault lay elsewhere and the capacitor failure was a consequential result.
