Matching coils
« on: September 12, 2010, 07:44:41 AM »
I have a corvette with the coil melted (same as pinball ninja http://www.pinballninja.com/?p=4279&cpage=1).

The part no in the manual is SM1-28-900.

The closest i can find at the site sponsors is a SM1 26-600 - will this be OK?

I'm assuming the 26-600 would have less windings and therefore a bit more power....maybe?

Thanks

Rob

From memory when i did electrical engineering ( and im sure Beaky will step in if im a bit wrong here).
Current is (voltage multiplied by number of turns) then divide this by cross section surface area of wire.

the 26/600 has less power due to gauge of the wire
