since it is always good to use stupid mistakes as learning experiences, I thought I would start a thread where we can share and hopefully learn from each others mistakes. And best of all maybe someone will have a suggestion on how to avoid the mistake in the first place.
So I'd like to nominate myself for today's Idiot of the Day Award. (although I did see a post earlier where someone lent their ski to their brother and their brother didn't put the plugs in and sank it so it could be a close race). Incidentally, before I get into my stupidity of the day - when I take my boat out of the water at the end of the season, I have a tag that I attach to the steering wheel that says "DRAIN PLUG REMOVED".
OK, so I go to fire up my skis today with the intention of testing the voltage regulators since I have a history of battery problems. I start with the '97 GSX with the battery I had to charge to get it started last week. I'll also mention I read an article last week about how when skis sit for a long time the MPEM will very slowly drain the battery so starting last week I decided I would disconnect the ground wire from battery when I won't be using them for a week or two.
As could be predicted I connected the ground on the '97 and it won't start, battery is dead so I put it on the charger and move to the '96 GSX.
I put a brand new battery in the '96 last week and it was starting instantly and running great last week when I left. I connect the ground wire to the battery, hi the start button and it cranks and cranks really strong. Start to scratch my head because I've never had a ski crank this strong and not start, I mean nothing at all.
Ok, I'm thinking it has to be spark or fuel. I check the fuel filter, its got some brown debris in it, so i give it a cleaning and the ski still just cranks but not fire. Next I pull the spark plugs, I'm not really good at knowing when they need replaced or not but I got 2 new one laying around so i stick them in. (I'll post pictures of the plugs I pulled out later just for input on how they look). Try again, ski still dont start. Ok, Now I'm thinking I've read thousands of posts on this forum I can figure this out. what next, I've got it. Pull the plug wires out of the boot and cut 1/4" off that will do it. I pull the wires out and they the ends look they have certainly seen better days, this has to be it. I cut the wires. Looks like some carbon buildup isnse the boots so I spray some liquid wrench in there and clean them out a bit. ( I didn't thing carb cleaner would be good for the rubber?) I stick the wire back in the boots reinstall on the plugs and the ski still don't start.
Now I'm to the point where I've done everything I can think of off the top of my head and I'll now have to consult the forum to see exactly how to determine if I am getting spark at the plugs and fuel to the carbs.
OK now the stupidity bell goes off. I'm standing there looking things over one last time and I see that I only connected the main ground wire, I left off the one that goes the the elec box in front of the battery. In my defense, the '97 ski only has one ground wire and the '96 ski has two but the lack of concentration cost me 90 minutes.
Connected the 2nd ground wire, ski fired right up and the good news is I was reading 13 volts at 5500RPM so my regulator is good.
Still waiting for the battery to charge on the other ski to test that one.
Anyway my question is this. After having done everything that I did (and assuming that I didnt forget to attach the 2nd ground wire), if the ski still did not start, what should have been my next steps to determine if I was getting proper spark and fuel delivery?
On my lawn tractor I would just pull the plug, connect the wire and turn the key to see if the plug sparks but I'm guessing that method wouldn't be appropriate on the ski.
So to be better prepared for next time, I'd appreciate some input, on first is what I did correct and what should have been my next steps if it still didn't start?
Thanks.
