Went out to the garage a few minutes ago to crank the 430 and it would not start. It has been colder than normal in North Alabama and is forecast to be in the teens at night and thirties during the day.
At start-up, the check came back 'OK' but the battery was too low (I'm guessing) to make a complete turn due to the cold. The garage is about 50 degrees. I last ran the car six days ago (it was fairly cold then) and I try and run it at least once a week for various reasons.
Question: should I get a battery pack and try and crank the car today or should I wait a week or two weeks hoping for it to warm up and try again? Also, the garage will not get below freezing regardless of temps, so there is no danger there. Battery is not on a trickle charger...
Thanks in advance!
I would absolutely do NOT jump that battery
: May possibly fry your ECUs which has happened to many [perhaps even my 456 couple months ago which is why it's being carted off] 360's, 430 and such.
IF on the open road, I would have someone connect up [if new battery can't be found] and have it trickle charge for a long time, AFTER taking their cables off your system. These cars are that much concern.
Put a charger on it, let it sit for at least a full charge indicator, and then start it.
Then, always keep a charger on it: FofSF even recommends it and will install, for new/warranty cars. For about $80 you are good to go as leaving on charger is NOT a problem. PS:
IF you have experienced a dead battery, then your ECUs need to be 're-booted' for lack of a better term.
I believe manual states to
1. turn key to on, but not start position for at least 30 seconds if a bit longer
2. turn key to start position and let car run for at least 20 min. for it to re-adjust the firing and control intake
and outlet systems.
3. drive moderately for a [great? 30 min?] time. <-- I am vague on this but usually drive under 3,500RPM for about 20 min.
Not to worry too much on temps, as fans should/would kick in etc. but, then again NOT good to idle run for over 20min. too.
Greg should be able to expand on this and
[what happened to
] Dave Helms, should chime in too.
