2003 HPDI 175 Rectifier/Regulator Repair

Greetings,

I just fired up my motor after a long cold winter and noticed water coming from the R/R housing, the R/R unit now has horizontal crack in the cover. Ironically this is the first winter I paid for indoor storage, but we had 40 days where the morning temp was below zero, so I guess I am not surprised it cracked.

Questions:

1. The whole R/R assembly costs $275, but the cover is only $35, can anyone tell me if it's just a broken cover or when this unit froze did it likely trash the whole R/R Unit. If I tear it apart, can I visually tell if the R/R is spent?

2. If I choose to do this repair myself, it looks like I have to remove the whole fuse box assembly to unbolt the R/R bracket (complicated by not impossible, right?), but what other things should I be aware, other damage to look for?

Thanks!!!

Most likely just the cover had residual water in it and froze and cracked.
To check R/R is to test diodes in it with a multimeter. If the R/R is cracked (the housing or the hard plastic sealer) it may be bad.
