Alternator question

[moo snutz]

Hey All -

 

Just ordered a new 8.1 / ZF with dual batteries and the hi-output alternator (145 amp). I haul a heavy slide-in & run some accessories, so I need all the juice I can get.

 

Dealer called me & said factory has just stopped offering the 145 as an option but that they would drop one in for me when the truck is delivered & would only charge me for 1/2 labor and parts, as it "wasn't really their fault". Not trusting of dealers, how can I verify that they did put the new alternator in the truck? I don't see any tag on mine listing the amps. Should it be larger than the standard 105? I don't want them to try to pull one on me saying they installed something that they didn't & then take my $$.

 

Kinda a screwy question. Sorry -

You should be able to cross refferance part numbers. My concern would be the buss wiring because I do not know if they upgraded wire size with factory 145 amp alt of not. Also fo what it is worth, I have plowed snow for years with GM trucks with stock 105 amp alts and dual batteries and I have never had any power problems and plow pumps are tuff on electrical system. THe dueal batteries you have will hemp you more than the alt will,

My 145amp says 145 stamped right on the case. It is bigger than the 105 and I think the pully is different.

I just lick the leads. If it makes me crap my pants, it's a 145 amp.

The 140 amp one has the external black plastic fan behind the pulley. The 105 has an internal fan.
