It's about that slow starter...

Our newest acquisition had a couple of symptoms that did not appear
catastrophic...

troubling, but not debilitating...

1. The starter appeared healthy, but it had to crank somewhat longer than
normal in order to start the car...

2. The A/C auxiliary cooling fan seemd to operate in a whimsical
fashion.... running for no apparent reason, and switching on/off
arbitrarily.

The temperature dipped lower this past week, and the starter becam more
"labored".

leading us to suspect the charging system.

The battery appeared normal, but a couple of days of survey testing
(carried the handy sunpro tester around..) and it would loose charge
gradually, even with the negative ground completely disconnected...

The terminals were clean and appeared normal...

But the battery commensed to drain enough overnight that it wouldn't start
in the morning.

So we disconnected the battery and pulled it out...

Battery acid everywhere....

here's the fun part...

Has anyone else noticed that the A/C system on the 2.2 liter engine bears a
striking resemblance to an angry octupus attempting to strangle the life
out of the engine compartment..particularly in the area of the battery...or
is it just us??

(oh sure...try to check the oil...!!!)

It seems that at some point in the life of this car, there was enough
battery acid/corrosion seeping down over the side of a battery to corrode
an enormous hole in the a/c sensor/fan switch that lives between the front
side of the battery and the front grille (VERY tight quarters..shame on
those designers..) and the ailing switch rubbed on the side of the
battery... prroducing a small hole in the battery case....

You can't see this switch.. and everything appears normal from the top of
the battery...

I should scan this poor little switch....looks like a monster took a chomp
out of it... wn this poor little switch....looks like a monster took a chomp
out of it... we bathed it in baking soda solution.. looked like a volcano
eruption for several changes of the solution.

It is the most pathetic looking critter I've seen coming out of a 505
engine compartment in a long time.

we now have a new battery... and we'll worry about re-connecting the a/c
fan next August...maybe...A/C has about as much value in Maine as snow
tires in Florida(this is of course...only my humble opinion..)

I just thought anyone who owns a 2.2 liter 505 might want to see whats
happening around their battery.

The corrosion on ours looks like it took several years to deteriorate to
its current state...

sad to have a slow and painful death occuring right under the hood of your
favorite peugeot..

it never ends....

tamara

just too many 505's to think about all at once..
