Ive been on youtube/google for about 2 hours now and finally found this video. I cant find a good pinout for the main plug on my merc 800. It has a distributor just like this setup. I probed around with 12v and couldnt get any lightning. I DID NOT put 12v to both those poles like you did here.. hopefully my boat motor screams tomorrow. Thank you for this.
Hi Terry, re the Tractor piston (manufacturer) I sent to you.I dont know why the info gets removed on you tube. I will try to send this info again on this other video reply... It is J.D. Pistons at 25 Innes st windsor gardens Adelaide south australia 5087 Australia... I twice sent this info,but it doesnt come thri i believe... If not agaain I can always send my email info. I am very interested in old Mercury motors,I have a 1967 110 Hp that has been reconditioned by others.
Yes but it is a very time consuming process. You have to dig out a ton of potting Material to get to the board. It took me days to free the board it the one I did
Hi Gremlin When I power up (key on) the switch box on motor , I get 12V on red but only approx 0.5V white, is this a problem with the ignition switch or normal ? I have a Mercury tester like yours but it died yesterday doing the coil switch box test , now looking for good replacement. Great I found this video so I can keep going on finding my no spark problem which I believe is distributor related, replaced the trigger for a tested one but still no spark at 1, need to have a good look at the cap, rotor and pin.Old merc I6 fan in Australia :)
do you know where I can buy a few feet of the color coded wires for a merc 650 in the 2207872 series or 2872319? red, yellow, gray, black, salmon, white and brown?
Okay I have a question. I have a Mercury 115hp with the same switch box. I have all the wires hooked up correctly but I’m getting low voltage on the distributor side connection does that mean my switch box is bad?
1st problem seems like just the starter solenoid. But my ignition key is busted so I did change it, but since then I can't make it run again. You said in this video if I made wrong connection some parts will burn because I don't have fussed, so do you think I did burned it? And if Im to put fuse how much should I put? This is my first motor, merc thunderbolt 500 50 hp serial 2347494. Bought it a month ago thinking it is a quick fix. I m interested in working on it but I am really struggling right now any advice and help would be very much appreciated. Thank you in advance
This is the perfect video for testing dizzy, coil and switchbox

Hope this helps
@@Terry2theGremlin it did, i posted a vid of it running on my channel. Thanks again man, couldnt have done it w/o this video lol
Good video, learned a lot.
Hello! Big fan - can you help me find a source for learning how to use the mercury ignition analyzer mark I?
@@andrewsheneman2135 let me see if I can find my book on that
Great video! What if I hear that spark noise but my starter is not turning over? I've replaced the starter solenoid already and no difference.
Thanks for sharing helped me a lot

Hi Terry, can faulty switchboxes be repaired internally? Thanks
Yes but it is a very time consuming process. You have to dig out a ton of potting Material to get to the board. It took me days to free the board it the one I did
Sir can you please tell me test procedures for that coil?

Check out the trigger/coil/switchbox test video from masterknowitall. Seems like a very easy test
How do I test trigger without switch box
do you know where I can buy a few feet of the color coded wires for a merc 650 in the 2207872 series or 2872319? red, yellow, gray, black, salmon, white and brown?
Not sure anymore maybe CDI
How do I test HELP!!!! Please
