(ET) Sparks!

[tb <tbamc gbta net>]

I was having problems getting my E12M to move forward and traced it to a 
bad micro-switch.  Replaced and all seemed ok for a short time.  Now, no 
high speed (2A).  2A coil has 38v, but no v on its contacts.  Wanted to 
check for voltage on 1A contact which should feed 2A.

With drive motor running in 2nd speed, but lever in high, I touched meter 
probe to the 1A contact (wire #7), got sparks and nearly burned my probe 
in 1/2.  Am fairly certain the probe wasn't touching anything else.  
Before I ruin a good Fluke meter, or its probe, thought I better ask 
what's going on.  :-)

Was current being diverted from R2 through the meter?  Or?  I should 
mention I replaced 1A (needlessly) when doing the original 
troubleshooting.  It's a slightly different style contactor than the 
original but don't think it explains this.

Thanks.
