Hot ignitors

[Zukijames]

Finally getting my. Project done and noticed after running for a min ignitors are too hot to touch

Do they need to be mounted to a heatsink?

 

[cribbj]

Definitely would recommend heat sinking the ignitors. Are your coils getting hot as well?

If you're running a standalone you might want to cut back your dwell settings a tad as you might be overcharging the coils and that'll take out coils, ignitors or both.

Coils don't get hot I will try heat sink do they need to stay together or could a mount them individually

 

[cribbj]

You can mount them wherever you can fit them. If you're using one per bank, then it would make sense to put one on each side of the engine bay. I'd mount them where they'll see a bit of airflow and you should be good.

I think I will mount to heat sinks and run small cooling fan from a computer

"whoa, these were REALLY hot igniters!!!! I shouldn't have been running 1UZ conversion!"

 

[Zukijames]

Hahaha that's about how hot mine are

I'm wiring a fuse and relay between my ignition switch an ignnitors hopefully that well help a little

i took a desktop power supply apart , hooked each ignitor to a heat sink inside the power supply box wired up the fan to my ignition switch things seem good now
