coil resistance chart.gif

OK, I'm about to rebuild the flippers on my Jurassic Park.

The manual calls for 090-5020-30 coils on both lower flippers

I have new 090-5032-OT coils (same as the ones on the lower flippers of my TFTC)

Can I use the 090-5032-OT coils instead of the 090-5020-30 coils on both lower flippers of JP?

Are they stronger? Weaker?

What's the diff here?

It's 22-1080 (090-5032) vs 23-900 (090-5020-30)

Thanks,

RussMyers

If you have both coils on hand you can use a resistance measure to get a basic idea if one is stronger than another.

In general, less resistance = stronger coil.

Should be close. Maybe a little stronger and less likely to fade.
22-1080 (090-5032) 4.2 Ohms
23-900 (090-5020-30) 4.05 Ohms

Stronger should be at the top.

Where's that from? Stern site or manual?

That's nearly identical - should be good to go.
