I may have some really dumb questions coming. I know Johnson Evinrude like the back of my hand but not Suzuki. I have spark on the starboard side of the motor only. According to the manual I have tested the following using a DVA.

1990 DT150
Serial # is 011202

Red White to Ground 3.7
Resistance 191
Red Black to Ground 4.3
Resistance 236
White Black to Ground 3.7
Resistance 201

Black Red to Green 160
Resistance 279
Red Black to Ground 0
Green to Ground 0

Orange Green to Black Green 3.4
Resistance 194

Swapped the coil leads and got spark on the opposite side.


I have read where it could be a sensor for low oil or something like that. I don't even know where those are, much less how to test them. If I am correct it looks like my stator and trigger test good. I have a parts motor from a 1996 DT150 but the CDI is not the same. Any advice on where to go from here would be greatly appreciated. Is there somewhere that I can look for parts for this motor?

Ok I know that someone will eventually read this and have some answers so...................

A. I found Brown's Point so I am good there.

It appears to me that the wrong CDI is on the motor. It has the longer one and everything I am reading says that a 1990 should have a smaller one. I am assuming this could cause my problem. I am attaching a picture to show how it looked when I got it. There was a wood screw holding the CDI mounting bracket up. Can someone confirm that maybe I have the wrong CDI?
