DVA Values For late 70’s Suzuki

[shane-r13]

Hi All,

Back again. I had posted earlier about a no spark issue on my 1978 Artic Spirit (Suzuki made). I have purchased a DVA adapter for my multimeter. I’ve obtained some values but don’t know what they should be. Ive read that it should be similar to a mercury value? In all honesty I’ve never had to diagnosis a CDI ignition before so i’m not sure what wires i should be test. Example trigger to trigger wire or one trigger wire to ground etc.

So far I have,
One trigger wire to ground – 188volts, the other trigger wire to ground – 177volts.
Charging coil to ground is 9.78Volts on one wire, other wire no reading.
CDI to igniton coil wire and ground – No reading.

Just from an assumption seems like my CDI is bad, hence the no spark?

Any tips, pointers, advice is as always appreciated!

Thanks,
Shane

I am sorry I only have the following:

Chrysler
Force
Johnson
Mercury
and Yamaha

I did find this, so if Suzuki used one of these you are in business:

Re: DVA Voltage specs needed

Thank you very much. I had no idea that Yamaha and Suzuki were the same….

Gives me something to do today!

And I hope this is what you need

Thanks Richard. Now to just decipher the colors and what wire is what between the two as i’m sure Yamaha used different colors than Suzuki. They wouldn’t want to make it easy or simple.

What are your thoughts on no voltage from the CDI unit?

Thanks,
Shane

Honestly I have no clue, it was info I found a few years ago, and kept it, Not one single motor in my collection uses that kind of ignition… my faves are Battery Ignition RBM’s so I am not much help.

I wish it didn’t use this ignition as well. But its a great motor for what i use it for….when it ran.
