Topic: Washed the bike, now it won't start !? Update & questions !

Looks like it's probably time for new plug caps. It's arcing through the plug cap and jumping to the valve cover/head which prevents the spark plug from creating a spark where it should and thus no combustion event --> missing.

Well you are pissing uphill until you fix that spark leak and if you have one you might have others you have not seen yet get that sorted

Not sure ehat you mean.
To be clear, that spark arch is only occuring in combination of water. The bike runs great otherwhise.

It is just a American saying or slang meaning if you piss uphill it will run back down on your foot so you need to take care of it quick. Also don't eat yellow snow

It seems that you keep showing #1 cylinder as the culprit for the arcing from the cap!! move the plug cap to another cylinder say #4(easy to see) and check to see if the arcing from the cap moves to #4 plug... The plug caps are not that expensive (here in the USA) about 5 USD.  With the stock coils the wires can become brittle  and cause arcing when wet also, the bad part with stock wires ,you have to replace coils or do a splice in of new wires. As already mentioned , with the wires DRY spray all the wires down with silicone spray, this will insulate them from the water and prevent the arcing.

Friend, I would like to know how this connected collector signal (which replaces points)

[yenko25]

the blue and white wires coming out of the pickup where they go? go direct to the coils? They reach a CDI? I would like to know the connection diagram

It could be here, check it out:

Thanks 70cb750.

I have the wiring diagram.

What I would like to know is the installation or electrical diagram adaptation to eliminate Points Spark, and install Pickup CHRYSLER in the CB750 of Viktor.J

I'm interested in this adaptation

[scottly]

Yenko, we never found out the origin of the electronic ignition system on Viktor's bike; it is not simply adapted from Chrysler parts, but made for the bike, using a similar style pickup.

There module connected to the pick-up coil?

I not stay clear connection pick-up coil.

wires are connected pick-up module, or the connection is made directly to the coils high?

wire blue and white are connected to the coils high? or connected to module?

[scottly]

Some sort of module is required to boost the weak signal from the pick-up to the power levels the coils need. The SOHC 650 models used a similar style pick-up, with modules to drive the coils, but it is not easily adaptable to other models.

[yenko25]

excuse my insistence. I'm curious and I want to know if there is another option besides dyna Or another commercial electronic ignition.

I found this. Apparently it works

I had never seen a pick-up

[scottly]

Yes, GM modules can be used with the 650 pickups, and they can also be triggered by the stock points to create a hybrid electronic ignition, such as member Hondaman makes. The advantage of this is to reduce the current through the breaker points, which greatly increases their life. An all electronic alternative to the Dyna is the Pamco system. Which model bike to you have?

CB750 K3

I want to test with a home electronic ignition

[scottly]

Here is a picture of a 650 pick-up plate next to a 750 points plate.

A friend has the CB650, recently was damaged. We had to replace them. OEM buy.

Since that time I woke doubt if my cb750k3 could you install these pick-up.
