    Cap & diode in DC environment

    Well, I don't wanna jinx it (again) but it seems the battery was the culprit. Two days of standstill, temps are 32F and lower, and no more resetting. Woo-hoo! I left the caps & diodes inside, I guess they can't hurt... Once again, thanx for all the help and ideas!!

    Cap & diode in DC environment

    It did discharge once, in July, when I left interior lights on for 2 days. But in summer. Maybe that killed it. Anyhow, I got a good quality Varta now, and a new one for the broken, in warranty. It's got 2 years of warranty, so it's in the ads maybe I'll manage to sell it since it's brand new.

    Cap & diode in DC environment

    Batt was bought 11.29.2010. and disn't have problems untilthis september. Now I jumped it to start, went to the shop (20 minute drive) and it didn't recharge to crank it again. So They tested it and it's shot. Got anew one and now I'm gonna replCe the old one under warranty & sell it. They also...

    Cap & diode in DC environment

    As tight and as clean as they can be. Tha was the first thing I did back in late september when the clock-resetting started.

    Cap & diode in DC environment

    I drove last on moday evening, clock resetting & everything. But no other problems. Today (thursday) around 6 pm I went to doctor's only to find I can't crank her - fast clicking from starter and all lamps dimming. So I guess batt is shot, and maybe all my problems were with the batt afterall...

    Cap & diode in DC environment

    It didn't happen in summertime, not once. It began with autumn temps, when they started being under 12C (53F) the whole day - meaning lower in the morning, of course, and up to 12 C (53F) in the coldest part of the day. ---------- Post added at 11:49 ---------- Previous post was at 11:48...

    Cap & diode in DC environment

    ^ will try that, on saturday morning 'cause I work 8-4:30 and don't have any daylight nor garage, so weekends is the only option. Unfortunately, due to two big connectors that go to the computer, I can't move it far away from its post - just 3-4 inches maybe, not enough to reach the seat. I...

    Cap & diode in DC environment

    And what is that, this SMPS power supply? ---------- Post added at 16:29 ---------- Previous post was at 15:31 ---------- OK, I Googled it :) Waaaay to much for me. I understood that it should be a device that would accept input power of 5-15VDC, and give constant, clean, spikeless 12VDC...

    Cap & diode in DC environment

    I just checked the wiring info - the darn thing has 3 GND pins, all 3 going to the same splice. Which is, of course, in the engine compartment, well covered & hidden. So I'm gonna have to manually override the GND for all 3 pins to a known good GND location (like a nearby bolt going through the...

    Voltmeter connects in parallel with caps? Or in series?

    Cap & diode in DC environment

    When cranking: if I turn the key to on, clock is ok. Then I crank, the engine comes on, and the clock resets.

    Cap & diode in DC environment

    Well... Same thing again. After 5 days no reset. That was saturday. Today, monday, it reset again. I don't know what to do, I don't have any more ideas. I belive 30000uF combined with three diodes with a total of 23.5 amperes would be an overkill for such a thing, but it's obviously not. I am...

    I needed help and ppl here helped me out. Saying "thanx, it's OK now" is the least I can do. And pulite, too ;) I will be reporting again after a month or so, of course!

    Cap & diode in DC environment

    So, it's been 5 days since I didn't drive. Went yesterday, and all was well! Clock & date didn't reset, obviously the caps held good. Temps outside were from some 32F in the coldest part of the morning, up to 55-60F in the warmest part of the day, so no too much trouble but nevertheless, the...
