Hi,
I'm new to this forum. Seems like a lot of people with experience of the MC60 power board.
Mine is from a treadmill and all works except for the belt.
When I took out the board I could see that one of the resistors had a broken leg. (R37)
Then I noticed a second one also broken. R38.
Is this normal?! I thought resistors could blow but not break.. or is this what happens when they blow in a normal operating condition.
Excuse the newbie question......
Anyway, after using resistor color code calculator I've calculated that the resistors are:
R37 - 794 ohm (1% tolerance)
R38 - 6.2M ohm (5% tolerance)
I problem is that R37 does not match the value in the schematic I found on this site.
It has R37 as a 230k Ohm resistor - but when I check the color code for that it doesn't seem to match my board.
Help!
