I've had a Batt Shack 160amp alt installed since beginning of last season. No issues. After the Batt Shack saga came to light I planned on correcting the issue. I pulled the stock 55 amp alt that came in my MC to look at it and noticed theres no screens on it. Now I'm really confused. Is this the brushless vs non brushless-screened vs. no screens situation. Just not sure which way to go with this one
Screens are not necessary if it is a brushless alternator, since the brushes are what cause the sparks that require arresting. My factory alt has no screens either, it's simply a brushless one. Should be fine.
