<DIV><FONT size=2>Thanks, Bob. I've a few different coils with appropriate
date codes for my car. Is there a way to test the different coils with a DMM
to tell which might be hotter? Do you have examples of the two different '64
coils you could run meter tests on to see? I'm also curious where the hotter
coil info is documented.</FONT></DIV>

<DIV>Hi Shaun,</DIV>
<DIV>The # 172 coil is the hot one. I know this because I ran a series of tests
to measure the spark output of various Corvair coils. I know of no simple means
of measuring coils to determine this. For years i went around measuring
different coils with a DMM and got lots of different readings, but no pattern or
conclusive findings. The only thing that surfaced was that all stock Corvair
coils agreed with the Shop Manuals specs.</DIV>
<DIV> </DIV>
<DIV>What settled this for me was that I borrowed Bob Ballew's little tester
that has a 12v. battery motor driven cam turning at about 1K rpm operating a set
of points and ballast res. The coil to be tested is installed and the output
sent to a variable spark gap. I used a digital caliper to measure the max gap
for each coil being tested. We had a large set of coils to be tested.</DIV>
<DIV>This so far isn't documented anywhere except in the 2nd edition of my book,
Corvair Secrets, now available at $24 from me PP.</DIV>
<DIV>Regards,</DIV>
