Thanks for the info Tony. The reason I needed the information was to verify
the part was bad, the unit is 16 miles from the shop. On the first trip I
measured the voltage on the chip because didn't have the right one with me,
the info you provided has verified the IC is bad, I didn't want to waste
another trip not knowing for sure.
Thanks again,
