Yes, amps are just as
important as volts, but when your volts start to go down, it's a pretty
good indicator that your not producing enough amps to maintain
the voltage level. (too much current draw for the available output,
hence you get a "brown-out") At full voltage lights burn brighter,
ign. works better,all power accessories work more effeientlty , my cd player
actually shuts off if the voltage falls below 12. I will probably never use the
full 86 amp output, but alternators that have high out-put at the
rated rpm, probably also have higher out-put at idle to low rpm as well.(at
least the one I chose seems to have) It's clear to me that the original
1967 single field alternator (which probably had a max output of 35 to 40 amps)
just was not able to fully power all the stuff on this big car, and to be fair,
in 1967 that was probably as good as it got. I use these cars as daily
drivers and expect them to perform as well as they can. As far as the ampmeter
goes, on these older mopars I recommend to bypass it irregardless
of how many amps their system can produce, here is the reason, the way Chrysler
designed these systems, the full output of the charging system is sent from the
alternator thru the firewall, up under the dash to the ampmeter
and then back thru the firewall to the battery, all with no short-circuit
protection(fuse). I have a 77 dodge truck in which the ampmeter
melted-down and caught fire while I was driving down the road ! , in doing the
repair to it, I studied the wiring diagram and saw how dangerous a design
it was, our imps aren't much different.I have heard of other old mopars burning
up due to the same design flaw. In fact if you look at the ampmeter in my 67
lebaron, you will notice that it sits slightly crooked in the
panel, (just like my dodge truck did) because the heat over time is
deforming it. I am not going to wait for it to do what my truck did. Sorry to be
so wordy, Just trying to fully explain and maybe save some old mopars. Best
regards, Mike
