On a 2000, is it necessary to maintain 12V to the system while changing a battery? grant - Tuesday, 12 February, 2013, at 8:22:40 am |

Any harm to sensitive circuits charging through the lighter circuit coincident with battery out? Laz - Tuesday, 12 February, 2013, at 11:49:43 am |
Charging as in a 9 volt battery, no problem. mikefocke, '01S Sanford, NC - Tuesday, 12 February, 2013, at 1:56:43 pm |

Let's be more fclear. DONT TOUCH ANYTHING! JUST SWAP THE BATTERY grant - Tuesday, 12 February, 2013, at 2:44:43 pm |
I dont think so. grant - Tuesday, 12 February, 2013, at 2:43:12 pm |
Thanks, Grant. *NM* Laz - Tuesday, 12 February, 2013, at 3:46:18 pm |
however, see my typo-strewn comment above about being clear - where i added caveats at the end grant - Tuesday, 12 February, 2013, at 5:37:12 pm |
Ich verstehe schon! *NM* Laz - Tuesday, 12 February, 2013, at 5:40:32 pm |
Well, there is more to it that the loss of some learned values etc... MarcW - Tuesday, 12 February, 2013, at 11:53:44 pm |

Sounds like its a "nice to do", but wont do any harm to lose those values every 5 years.
The only hurdle is that i'd need to go to radio shack and make myself a cord with alligators on one end and a lighter plug on the other, and 20" of wire int he middle. Just more to do. but i may!
I've been through those re-learnings on the red car 6-7 times in the last few months as it came back together.

Yea, i suppose.. I was thinking yesterday.... grant - Wednesday, 13 February, 2013, at 10:58:47 am |
Might the fuse box charge terminal have some surge protection? (edited) Laz - Wednesday, 13 February, 2013, at 11:03:23 am |
Just so it is clear I'm not qualified to comment on your MarcW - Monday, 18 February, 2013, at 9:21:27 pm |

..that the way to overcome the problem of battery-differential (if i hook a 10.5V dying battery to a new 12V battery via the lighter) is to put a 10 ohm resistor in series. For normal draw the drop will be insignificant. But it will prevent a surge, since the worst case scenarios is, say 12-8v = 4V/10 ohm = 400mA
Given that the normal draw is likely well under 100mA, the voltage drop should be less than 1.2V
Any bad assumptions here? This way i can connect them before removal, eliminating any "break before make" loss of power.

The windows will work (go up/down ok) but the window limits need to be reset. Consult.. MarcW - Friday, 15 February, 2013, at 3:11:47 pm |
Nope. On full run up and down (each) and they are all reset. grant - Friday, 15 February, 2013, at 4:14:18 pm |

Thank you. *NM* Laz - Monday, 18 February, 2013, at 6:04:54 pm |
I do plan to build one. But my experience on two cars now is you can disconnect at will. grant - Friday, 15 February, 2013, at 6:52:21 pm |

The partial-down stops work. The open/close works. The one touch works.
No issues whatsoever.
Running very smooth.
Very soft compared with "my" car.
(kinda nice on the road!)
I'll do the recalibrate, but is it effective no that the car's been used for a bunch of short trips?
