I don't know if anyone remembers. A while back I was having issues
starting the car in the morning. I use a primer switch and even when I hold
the primer switch when cranking it still won't fire right up , I need to
give it a bit of gas or it will quit. If it quits the second time it fires
I repaired the electric AAR over a year ago because it was not closing and
kept the idle high. I suspect it is now stuck closed , the reason is
because when I repaired it I would use the prime switch till I heard no
more air in the lines. It would fire right up and the idle would be a bit
higher , in 5 minutes it would drop back to 1000 RPM in neutral. Now when
it starts it's always at 1000 RPM. From what I recall the AAR acts as a
sort of choke by allowing in more air the MPS senses a vacuum leak and
enriches the mix. Always has to be something to fix. Taking the eclectic
AAR apart is not something that's in any way fun. I always read about the
people with FI who have the standard trans and the oil heated AAR having to
constantly clean and adjust them.
I haven't checked it yet , yet I bet if I blow on the hose from the oil
bath I'll find it is closed all the time. I can live with it , my main
concern is running down the battery. I don't drive far enough most of the
time for the charging system to charge it back fully. Most of the time when
I check the battery it's @ 12.5 volts . Drove it a mile yesterday, checked
the voltage and it was 12.97 after shut down. Once that surface charge
drops off I bet it's back to 12.5 or close to it. I use a charger set on 2
amps on a timer set for 2 hours because this charger does not have a shut
off feature . If it's 12.5 it takes 4 hours to bring it back to 12.7 VDC.
If I sit in traffic long enough I can see the voltmeter getting near 12.5
volts so I put it in neutral because @ 1000 RPM it's back up to 14.2 VDC.
I need to pull the battery just to check if the level in each cell is fine.
I check it once a year and last year it was fine. It's an interstate MT42
and the last thing I need right now is spending money on a battery. Even
when it's 12.5 volts it cranks over fine I think 12.5 is 90% charged.
