just a warning post. (12v battery problems... EOC)

I have noticed a 2.5 mpg drop in fuel yesterday and accompanied squeel at restarts.
The latter is not uncommon in the POS anyhow it comes and goes with the weather litterally.
But after coming to complete stop after key off Glide yesterday car did not desire to start.
I do alot of Key off glide about 1/4 of my 85 mile daily round trip.

The short of this story is combination issues, extreme use of coasting key off during morning run in darkness. High seasonal temps combined with grill blocks and belly "engine" Pan {exceptionally high temps in the Bay} add an underdriven pulley = Alt only charges at 12.9 volts and 49 amps. and prolonged use under these circumstances.

I recharged battery last night and measured volts checked belts etc.
The battery condition is still good but I havent gotten a recent amp reading from alternator. I just felt that others should understand these conditions b4 they take a weakened battery into upcoming winter months.

This Morning squeel was only upon start up, so battery has truly been beaten up by those combined effects.
