|Steve Andress said: (quoted from post at 15:56:58 01/18/13) I see NAPA sells IC7 and IC7SB. Both are 6 volt. The SB says wo external resistor. Is the only diff primary resistance? If so can you find out what the resistance is before purchacing?|
If you find a decent parts person at NAPA who knows the paper catalogs vs just computer, they can look up the coil specifics. I have stood there beside them & read the coil resistance specs in their catalogs. The SB (I think means Simple Black) is their so called 2nd line product, but for sure it means cheaper cost (~$18) than the non SB or 1st line ($50) coils. I believe the electrical characteristics are the same. Guarantee likely shorter. This post was edited by JMOR at 12:21:04 01/18/13.
