not charging
I have a 1998 Forest River w/454 on a p-30 Alternator that has checked out good. But not charging the system. Have checked wires and all connections for ohms and voltage coming from and to where it g...

There are often protective deices in the alternator lead, (Fuses/fusable link/Circuit breaker)
I would start with a charged battery (use external charger if you need to)
and then check for voltage at the BIG terminal on the alternator. if it is there hook a 100 watt 12 volt "Trouble light" to said terminal (And ground) put the other clip on the alternator housing, not the engine, not another ground, the alternator housing) bright light is good.
If you don't find voltage then back up the leads towards the battery until you do.
Problem is between voltage (or light) and dark
NOTE: THe reason for connecting the light between the alternator's big terminal and the alternator's housing... I've had a case were the alternator did nto ground properly.. The solution was to remove one mounting bolt, add a "Star" type lock washer (many teeth) and replace.
On a `1998 I do not think this next paragraph will apply but I've seen it on older vehicles.. FIVE TIMES (one was even mine)
Back in the days when the fan belt was a 'V' Belt instead of the modern Serpentine belts... Loose belt (on mine it was actually the wrong belt) lets the alternator pully slip
As I said. Have seen FIVE times.. Well 4+1 The 1 the belt was not just loose.. This was a brand new sticker in the window car and the belt was.. NOT,, Period. it was MIA, Factory never installed it.
