Good morning everybody.
I'm new in this forum (I just posted my presentation yesterday), but I'm in search for help for my '94 FLHTC.
The bike has been sitting in my garage for 3 months, while I was overseas, and I tried to start it last week, but there is no ignition.
I have been seeking for 1 week now, and I'm out of idea…
The coil is new
The spark plug wires are new
The spark plugs are new
I have 12v at the coil
The ground is good
Everything on the bike works
And yet, there is no spark at the spark plugs.
I am now stuck !
Has anybody any idea where to search ?
Thank you in advance, and have a good day !

12 volts indicates a dead battery!
Charge the battery until it's at 12.8 volts static then try starting the bike.

I wrote "12v", but it was just to say there is current. In fact, I have about 12.6 at the battery, and my charger considers it is full charged.

12.6 volts is sufficient. Remove the plugs, install the wires and ground the plugs to the heads and check for spark while cranking the engine over.

Do you have a battery charger or a battery tender?

A tender is not a charger, it doesn't have the ampage to properly charge a battery.

A battery with a reading of 12.7 VDC (volts direct current) is considered
100% charged, while 12.6 is 75%, 12.3 is 50%, 12.0 is 25%, and 11.8 is 0%

I copied this from a "shop talk" entry on our local HOG newsletter. It was written by the dealerships Master Technician.

I already did it several times, but there is no spark. The only thing I did not do is to check the ignition module. I just removed it, and I'll bring it to my dealer tomorrow, I hope they will be able to tell me if it works correctly or not.

It is a charger. I know a tender is not a charger… But I think that normally, as soon as the battery is able to make the starter crank the engine, the coil will will get enough current for producing sparks.

It is a charger, I know that a tender is not a good stuff for for charging fully a battery. But I think that as soon as the battery is charged enough for making the starter crank the engine, the coil will be able to make sparks.

Sorry for that question, but what do you call the "kill switch" ? :dunno

number 26 in the picture. It's easy to hit and not notice it's off.

Oh, yes ! I called it the "emergency switch". Of course, it is on. When it is off, the starter doesn't work.

There's no bench test for the ignition module, if it appears melted then it's bad otherwise it has to be tested installed on the bike.
Still no spark ???
How many miles on the bike ???
