Ah, meter good enough for Grandfather, good enough for you!!

Does Bob have the installation manual for high button shoes?

OWWWW!

Try this, put that digital meter on "AC" 10v and measure the "AC" that is "riding" your 12 or 24 volts "DC".  There will be an AC component unless "everything" else is disconnected or shut down.  No line AC connected to shore power either.  The reading you take on a battery should not vary any amt from one reading to another unless some time has passed or there has been some charging and it should always diminish.  My experience!

I once resolved a "phenomenon" concerning an add on electronic ignition.  Seems it worked if the B+ was connected to the bat terminal but it was erratic when connected to a B+ source at the other end of a 4 foot wire that was part of the original wire circuit.  Different ends of the same wire determined wether it worked?  Hmmmm.  I switched to the AC scale and found that one end of the wire had zero AC volts but the other had 6 or so AC volts of "noise" riding the DC.  Adding a capacitor would have resolved the issue but the ignition module was defective and replacing it made the install power source more tolerant.  The internal cap on the module was probably defective or not connected.  All I got for that was an "you SOB" with a grin from the owner of the shop.  And that was enuf.

Being a short school bus kid and electrically challenged I am trying to sort through this and hopefully do better in the future. The problem started last year when My battery monitor showed a low reading on my 2 grp 31 start  batterys set for 24V. I check with my meter and got a 24.X reading. removed the batteries and had them load tested. After watching the people at the store a couple more times, they do not know what they are doing!! One tested bad so I replaced both. The batteries were 7 trouble free years old so I did no further investigation.  I may have replaced a perfectly good but old battery.  They were sealed, in hindsigh with no warrenty I should have broke the seal and used a hydrometer.

I promise faithfully to never again comment on a serious or technical topic.

You guys crack me up! And yes, the high button shoes analogy definitely dates me.  Touche.

JJ,

A common and very old problem.... good/competant help is hard to find.  Good intensioned merchants are rare also.  Find those qualities in the same shop and you have a real "find".  If I only had a nickel for every time I looked back at a decision and said "Crap, If had just....."   And yes, I was married.

If I didn't like old stuff;

I wouldn't have bought several 54 year old buses. 

I wouldn't have bought a 73 year old house.

I wouldn't be collecting old garage stuff like Sun Machines, old headlight alignment tools, old front end alignment tools, etc.

I wouldn't have Bob as a buddy.

Hey, you said old.... not ancient!
