Unhappy No spark in front coil

Hello, I recently did some work on my 91 vn750. After putting everything back on the bike I went to start i t and was getting no spark in all cylinders. I checked the IC ignitor and traced the problem back to a loose stator wire. I repaired the problem and then the bike started..... for a few seconds and then cut out. I checked both coils, stator, IC ignitor with an electricla tester and they all were within the listed limits in the clymer manual. I pulled the from spark plugs and still am getting no spark. The rear are working just fine. Any suggestions would be helpful.

Have you checked your pick up coils? But it is probably your Tach. disconnect the tach in the HL bucket then start the bike. The tach. runs off the front coil and if there is a problem with the tach. it will affect the coil.

not another not firing issue...god I hate these...50 bucks and I will walk ya through it...lol..j/k...try that first link then get back to us... also what have you done to the bike...the most common problem with a cyl not firing is due to the pickup coils, or the wires coming out of the engine from the pickup coils.

Thanks for the responses. I have put a new generator gasket on, new handlebars, degoated and fixed several issues (missing screws, hoses, incorrect rebuilds, new air filters, ignition coils, and several o-rings). It was definitely more work than I was hoping. Anyway, I tried the tach disconnect and noticed my battery is also dead (probably form trying to get it to start). I did get spark with disconnecting the tach, so any ideas on what the problem is (possibly a lose wire or connection). The engine still would not start. I am hooping to charge the battery up overnight and give her a shot in the morning.

Thanks

Phil

Our scoots need a fully charged battery to start, If you have a standard battery throw it away and get an MF AGM battery, I will post a link below. Also ditch your standarg plugs an get NGK DPR7EIX-9 IRIDIUM plugs. The combination of the two your scoot will start right up!

With that out of the way lets get to the Tach issue, By the way the Info. is FREE but the solution will cost ya!! You can check the Tach wires but the problem is probably inside the Tach and is not servicable. You will have to replace the Tach!! contact Crobins365 She should have a Tach for sale. At the top of the page click search in the find member box type in Crobins365 and send her a Private Message. I would send you to Battey Mart but they are out of stock due to high demand. Advance Auto Parts also carries this battery under a different name, ask for ETX15L they are all made by East Penn Manufacturing. Man I cant't wait for my commision check!! I wish!!

Phil,
If your local battery warehouse is out of batteries like lance said, and you don't want to pay for shipping, check out your local lawn and garden dealership or atv dealership. That is where I got mine in less than a week.

DO you work at the battery warehouse- I work at a Kubota dealership and the Deka man comes usually once a week. I had no problem getting my battery. Good luck with that.
