keep blowing ingnition module

[Deeman21]

have replaced ingnition module three times runs for about 20 miles and then red light go"s out and won"t start someone told me i need to replace my charging system because the system is surging to meany volts i did replace the tachring because the tach wood not light up plus im running a lipo battery didn"t start acting up till i replaced the battery and the tach ring

What year, make, and model?

Since the ignition module was working fine before battery replacement and tach ring replacement, that means you have to go back and trace your steps.

Test the voltage and current on signal wire from tach to ignition model.

My first guess would be the charging system is not regulating the voltage and current properly.

I'd check the voltage coming out of the regulator for sure. Maybe it doesn't like the lithium battery, so its overcompensating.

I'm not sure what model we are talking about, but, these are ideas or food for thought.

ZI'd hook a voltmeter to the battery, rev the engine and look for over charging say14.9 - 15v.

Shows good say 14.4 - 14.5v I'd now go to the ground leads from battery posts, ground cable ends to frame ground.

The new tach ring could have potential compatability issues as well.

Examples:

Signal interference

Wrong pulse count

Voltage spikes etc.....

Try a plain ole Deka battery.

I don't think these bikes like those Lipo style batteries.

 

[Mickmorris]

Yeah before you mess anything else up… get rid of the LIPO battery. That’s 1st. When you get a new AGM battery installed put a inline fuse between your VR positive line& battery. You can test the voltage at the battery as Sven suggested or if your VR has failed and your stator is overcharging the system it will blow the fuse you have put in line between the VR & battery. Once you know that the charging system is working correctly you can focus on the tach ring as the culprit.

The lipo was not compatible with the charging system on my 04 Bulldog or my Shovel. I tried on both, then tested them. Neither worked, had to sell the battery.

it is a 2005 pitbull do you know what the voltage should be from the tach to the ignition module

thats what im going to do but i have to get a new ignition module to get it started +get a regular battery

have to get new ing module to get it running and unhook the tack ring and see if that work"s thank you

You had luck in the unluck.
Most not comparible charging systems dont charge the LiPo battery..
Nightmare is a high voltage overfill of the LiPo Battery.
Worst case is overheated LiPo burns and your bike burn down.
Tried a Panther LiPo in my 07 Pit Bull for a short time.
Works good but i didnt try the risk to burn down my bike.

I would make sure to put a fuse inline between your VR and battery BEFORE you try to start the bike again. In case it is your charging system overloading the ignition module…

 

[Savage 1]

That fuse will also protect stator and ecm Boss. Like Mick says, VERY IMPORTANT BEORE STARTING BIKE.

Remember to check the signal wire (green) coming from tach ring just for a sanity check.

May not be a bad idea to check the main power and ground to the ignition module as well.....

The problem started after you replaced battery and tach ring, it was running fine prior to the installation. I'd check both circuits, to ensure you don't blow another ignition module Boss.

Generally speaking, you could simply have a short on ignition wire circuit as well. We are not positive that the battery or tach are the problem exclusively.

Food for thought Bud.....
