Mad Dog Cycles Posted August 16, 2017 Share Posted August 16, 2017 Hello everyone, new here and & spent about 45 minutes combing the forums looking for a hint as to where I might locate the voltage regulator on this truck. My dad bought this on a whim, and it has been up to me and a mechanic buddy to fix the overcharging problem we had. We were able to get the old generator out and rebuilt, but we've been unable to locate the voltage regulator to replace it. Any insight as to where it's located would be greatly appreciated. Thanks in advance! Quote Link to comment https://www.bigmacktrucks.com/topic/50792-locating-voltage-regulator-1975-cf600/ Share on other sites More sharing options...

kevink1955 Posted August 17, 2017 Share Posted August 17, 2017 Behind the Drivers side Jump Seat, If there is a air pack holder you will need to remove it first, if not just lift up the seat back. Most have keyhole slots so they are easy to remove. If you do nor find it on drivers side try passengers side 1 Quote Link to comment https://www.bigmacktrucks.com/topic/50792-locating-voltage-regulator-1975-cf600/#findComment-377706 Share on other sites More sharing options...

kevink1955 Posted August 19, 2017 Share Posted August 19, 2017 Glad you found it. We spent the better part of a weekend back in 1985 looking for the regulator in our Tower Ladder. Monday morning a call to Mack and it was located LOL Quote Link to comment https://www.bigmacktrucks.com/topic/50792-locating-voltage-regulator-1975-cf600/#findComment-377859 Share on other sites More sharing options...
