After troubleshooting every other electrical component on my 1984 Honda Shadow VT700C, I determined I’m not getting spark because I have a bad pulse generator. Later model bikes use a single pulse, but the ’84 VT700C has two pulse generators, one for each cylinder. This equates to double the possibility of failure and headache cubed when one or the other it actually does fail, since they have to be replaced together as an assembly.
Testing the pulse generators is a pretty simple process of disconnecting the pulse generator assembly from the rest of the electrical system and taking an OHM reading on the leads for each pulse generator. The connector is easily assessable, tucked away on the right side of the crankcase by the fuel filter.
One of the pulse generators tested at 440 OHMs, well within tolerances. The other pegged out my multimeter, indicating a bad pulse generator.
Finding a “new” OEM replacement proved to be impossible. At least three websites claimed to have the part, but when I spoke to a live salesperson, in each case I was told the part was discontinued and no one manufactures a replacement.
I tracked down a used pulse generator assembly on eBay. It’s amazing that idiots like me desperate enough to spend $100 for a $10 part. Since the one I picked up was the lowest priced on eBay, and since the VT700 is scrap metal without one, I considered myself lucky.
While testing the pulse generators is easy, replacing them is a pain. I had to remove the right foot controls, the right-side exhaust, part of the frame, the right crank case cover, and both the clutch inner and outer.
Before installing the “new” pulse generator assembly and putting the bike back together, I decided to test it. Just like the original, it had one good pulse generator and one failed pulse generator.
In the spirit of Dr. Frankenstein, I began hacking at the two assemblies, tossing the bad generators in the junk bin and cobbling the two good generators into a single pulse generator assembly.
When I began routing the pulse generator wiring back through the crankcase, I discovered I had shorted one cable by half an inch. Clearances are tight in the crank case, with the wiring routed around several moving parts, so that half inch may as well have been a mile.
I set my Frankenstein’s monster of a pulse generator assembly to the side, and decided to take a break to check my email and check the status of some other parts on order from eBay. On a whim, I checked to see if anyone had posted another pulse generator assembly.
And there it was: a pulse generator off of a 1983 Honda Shadow VT750, for $15, plus $5 shipping. What did I have to lose?
This assembly arrived two days later. Both pulse generators tested within specifications, and it routed perfectly into the crankcase.
Now it’s time to button this thing up and see if we have spark.
At first I thought it was just an issue of leverage: it’s hard to get a solid grip the stator in one hand and the clutch cover in the other. I did manage to get what I felt was a good grip, and proceeded to twist and tug and turn and tap (and maybe bang a little), but that stator didn’t budge.
I got online and surfed the forums for a clue as to where I was going wrong. Did Ibmiss a hidden bolt? Did it pull straight off or thread onto the case (the new stator seemed to be finely threaded). My usual go-to site for the VT700C, HondaShadow.net, was silent on the issue.
I was tired, frustrated, and seriously considering parting the rest of the bike out on eBay. Then I did what I should have done five minutes after figuring out the stator was stuck: I called Big Daddy for advice.
He took time out of his shop renovation project (new drywall, new shelves, and an actual ceiling instead of bare beams) to listen to my problem. I texted over a few photos of the stator and clutch case so he could see the fresh batch of heartache I’d managed to find.
But, of course, Big Daddy had the answer.
He told me to head down to Autozone and pick up a can of CRC Freeze-Off, which is designed to dissolve rust and other muck that can cause bolts, screws and parts to bind together.
I picked up a $5 can of CRC Freez-Off (and another $50 worth of tools I don’t really need but probably will some day).
Back in the garage, I used the Freeze-Off ti liberally soaked the rim of clutch cover where the stator attached. I could see the grime dissolving and rinsing away at the edge, but I was skeptical about it actually penetrating deep enough to unlock the part. I started tugging and twisting and pulling again, but nothing happened.
I read the back of the Freez-Off can again, but paid attention to the instructions to “wait two minutes’. So I sprayed again and waited.
After two minutes, I got my grip on the clutch cover and stator, and I started twisting and wiggling. After a few seconds, I felt the stator shift a quarter of an inch on the clutch cover. I started pulling and wiggling some more, and with surprisingly little muscle, the stator popped right off.
CRC Freez-Off delivered on its promise once, but I had another test for it to prove if this was just luck, or if it actually works.
The clutch bolt where it attaches to the clutch slave cylinder was so stuck I was worried bout stripping the bolt if I put any more muscle (or body weight) into it. So I used the CRC Freeze-Off again.
It took a couple of applications, several minutes of waiting, and a little more muscle than the stator, but I managed to loosen the bolt from the clutch slave cylinder without stripping it or hurting myself.
So, CRC’s Freeze-Off gets top accolades from Oden Motor Shop.
