Hi everyone. I have a spoolinup kit installed for couple weeks now. Other day I turned the car off. Then got back in and would not start. I found I blew the factory 10amp igntion coil fuse.

I read a couple other posts that some people due to have this problem with non cop kits regardless of vendor. Is going to a 15amp fuse usually the norm to take care of this. I even saw one post Buschur mentioned running a 30amp which I am not comfortable with.

Just trying to get some feedback and see if this happened to others and their fix.
I spoke to Matt who was very helpful and said that should be fine running a 15a but to not go higher.
I just dont want to have to be worried about if the car is going to start every time I get in.

thanks

 

I have had the same problem man. I keep a spare pack of fuses in the car and change them frequently. I put 2 more grounds from the engine to chassis and it helps a little bit.

 

Which ignition coil fuse are you referring to?

#1 Under the dash?

Because this happened to me as well about 3 weeks of having my COP kit, and I replaced it with a 20 amp fuse...and haven't had any issues at the moment...going on about 3 weeks of replacing the fuse...

 

Yeah it was the under dash one, had a 10amp from the factory. Lasted bout 2-3 weeks

 

Odd...I was wondering if I was the only one that had experienced this...wondering now how many others have delt with this dilemma...

 

I Have spoolinup for abt a yr now. Never had this happen to me.but i have a couple of custom grounding so that might be helping.

 

So this is normal with the SpoolinUp kit? Interesting.

I hope the instructions tell you to upgrade your fuse.

 

I've had mine going on two years and have never blown a fuse so it's not normal.

 

Fuses blow, as long as it doesn't keep blowing. Think about it factory uses a 10amp for the ignition but you also only have 2 coils. You add 2 more coils and have a stronger spark. While some get away with not having to replace the fuse others blew the fuse just driving around the block after adding a cop kit.

First thing I did after switching to a cop was replace the 10amp with a 15amp. You might be able to get away with just using a new 10 amp fuse.

 

The sparktech non cdi comes with a 15A fuse and the instructions tell you to replace it, you are adding a little more load on the ckt as stated earlier.

 

Ok thanks guys. I'll swap out to a 15a when I get some time.

 

I found this thread to be very informative, thanks guys!

Is there any advantage or downsides for choosing a 20A fuse over a 15A fuse?

 

Interesting thread. I also have a SpoolinUp COP kit. I've had it for about 6 months, with no additional grounding. Stock 10a fuse is holding strong. Subscribed to see if others post with similar problems.

 

Well it definitly does make since needing higher fuse rating with the non cdi kit.

 

This is exactly right! Doesn't matter on vendor here. 4 coils draws more than 2. Easy math and no it is not a common problem. I recommend a 15a fuse with my system only with the AEM. It seems the AEM puts more stress on the coils for whatever reason. Very rarely does this happen with a stock ECU; always looking to improve I'll go ahead and include a 15a for everyone!
