Hello my name is ***** ***** am I speaking with?
I have a couple of questions back to you.
1. All Mercurys are cataloged by serial number, can I get the number off of this one so I can look up exactly which version of the 9.9 you have (they have been making this engine for 50 years)
2. Is the engine tiller control, or remote control with a separate key switch?
3. Do you have a decent quality volt/ohm meter, and do you know how to use it?
4. Are you near the engine now and ready to work?
Hi Cliff, the serial number is ***** the clamp bracket, starboard side.
Hmmm... If you pull the engine cover off, are there any stickers on the flywheel cover?
If not, can you take a couple of pictures of the engine for me, both with the cover on, and off.
Got it. Lets start with the stop switch clip. Pull the clip out, wiggle the switch, and put the clip back in. Does spark return?
Next locate the CDI box. Do you have a black with a yellow stripe wire that comes off of the CDI?
Disconnect that wire, and then check for spark again. Let me know if it returns or not.
Next, disconnect your ignition coil from the CDI box. Measure the resistance between the 2 smaller wires. And then measure the resistance between the larger high tension wires. What do you get for both sets of readings?
I don't quite understand you, did you disconnect the ignition coil from the CDI box?
The reading between black and orange should be 0.08 to 0.22 of 1 ohm, what did you get for a reading?
Without being able to do this on the phone it's going to take to long. It's already been an hour. I am going to opt out. good luck
Because your payment won't go through authorizing phone service.
