year, but given the length of the "to-do-list", it may well be a good
thing, as I can't stop driving this car.

ice and snow, but no salt!! Salt ran out in January having
received a record 98" of snow fall.

ground already )
Certainly a good year, with some longer (700mile) trips during the past weeks - it's going to be 10 years with this car. Even past 77,777 miles, and it still make kids smile and it still gets greetings. I can still look ahead by looking under those silly King-Kong SUV's.
I should really do some work on the car, but at a sustained < 10F for weeks now, I wouldn't even try change the oil, unless I used a spoon.
I know there's se7eners further North of me, so I'll save my complaining. The weather forecast is showing a warmup to maybe the 20F's, the week after next.
And... the new local low-salt road-maintenance policies should indicate early clean roads! Keep hoping.

Just wonder what it is with alternator brackets. The Valeo 45amp is very light, and the Zetec runs pretty smooth, maybe not at idle (light flywheel). So.. I dunno. Just replace it and see what happens.
I made the new one from delrin (as was the original from Raceline) a bit

The car has been very good this year. Over the winter, when it's not too extreme, I plan to check the rear suspension, as I still heard something make noise, although it doesn't affect handling. Maybe it's something with the wooden floor board in the trunk.... yes, my car has a 'trunk' :-)

Looks like three resonable choices:
PC545, PC625, PC680. No need for the metal jacket or terminals.
Picked the 680 for it's very low internal resistance (7 milliOhm) and good capacity/volume ratio. Although rated at 17Ah, it can deliver over 500Amps for 20sec. (or 680Amps for 5secs). Odyssee specs (220CCA), or 220 cold cranking amps at 0F and for 30secs.
Starters can't run for 30sec without taking damage. In other words, more than sufficient cranking power.
