hi, have a 1997 bayliner with 5.7 mercruiser thats only charging at low rpms. just replaced the second mando alternator in one year with the same results.cleaned every wire i could find and changed battery ends to those used on autos that crimp on cable. battery was replaced less than a year ago and starter alittle earlier.could battery go bad that fast and cause a discharge when tacking up or have i missed something? i feel ive replaced a good alternator since this ones acting the same .belt seems tight.also, was considering an 8D CAT battery and woundered if it would be ok to use with this 105 amp mando alternator. thanks for any insight, Douglas in North Carolina
