Sears Penske dwell meter
So being that I have a couple vehicles that still use point style ignition timing, I decided to buy me a dwell meter so I could accurately adjust the point dwell timing. I made my purchase off ebay, the purchase arrived within a a few days and I was really pleased how good of a condition this vintage piece was!! I was very excited so I jotted down to the garage to try it out on my c10 and Nova....well unfortunately it doesn't work. Taking it apart I found an old durscell made by Mallory, 4.3v battery, which looks like a fat AA battery....well of course this 4.3v battery is no longer available. I can find a 3.7v and a 4.5 v replacement. so now I come to my friends and experts on which battery would work well with this meter...will a 4.5v fry it, will a 3.7v work just fine??
I know there are some battery geeks out here that are shaking their heads in disbelief of my question....but your help would be appreciated thanks, Lenny |

Re: Sears Penske dwell meter
I would say either battery would work. I would bet there isn't any sensitive circuitry inside the meter that is going to care if the voltage is a quarter volt high and those meters probably worked fine until the voltage dropped past 50% of rated voltage. Personally I would go with which one fit the best. And if there's no difference there then cheaper one.

I did a similar swap for the sending unit of my Sun Tach.
Took some crap for it (on this forum, I think) but it seems to be working fine (it's been thirty years, I think). K Quote:

70 CST Short Wide: thank you so much for that offer, I'm hoping the battery will get this unit back up and going again?? Should have a battery in a week or so, if that doesn't help mine, them I may take you up on the offer...once again, thank you for that offer, that's one of the reason I love this site!
HO455: fitment is something I need to work out...finding the right size battery, I think I can spring the terminals to accept a slightly longer one, but the diameter is tight with capacitors and resistors on each side. Keith: those batteries look similar to mine, a fat looking AA, Mercury type....happy to hear that you had success, I'm going to try it! Thanks again for the responses guys...I appreciate it very much! |
