Detroit Series 60 Has Quite an Appetite for Alternators and Batteries
We have a 2005 ~455 hp Detroit Series 60 in our rescue pumper for which we are replacing one of the alternators for the second time in three years and the 6 batteries on the truck. It has dual Leece Neville ~270 amp alternators on it. The truck is multiplexed. Not sure if that makes a difference. We only run about 32 calls a month. It also have a shore power charger on it. Should we be looking to another manufacturer for replacement alternators? Some of my limited research talks about heat issues. Have these issues been addressed in newer model alternators. Our Macks probably needed a new alternator twice in 20 years.
