Title: battery overflow
Post by: MONTY59 on June 08, 2015, 04:25:43 PM
can anyone tell me are there other reasons, other than over filling, why the battery should start leaking out of the overflow tube thanks . [Dolph]

Probably over charging.

Bad R/R.

Start the bike and rev it up to 3K rpm. If the voltage at the battery shows over 14.5 volts it's a bad regulator/rectifier.

^^^ short and sweet.  buy a cheap multitester.

It's a common fault with the older single phase altinators keep the bike on trickle charge when not riding!

Buy a sealed maintenance free battery is the only real fix!

I replaced my regulator once with a Rick's and still use a flooded lead/acid battery.

No overflowing.

Overcharging is overcharging.  Yes, your AGM battery, unless it is one of those defective batteries Ducati and Yamaha used in the early 2000s will not puke acid but the valves will still open and your battery and possibly other electrics and electronics will be damaged.  The overcharging situation must be fixed.

I did come across a situation back in '74 where overcharging was caused by the battery itself.  "74 Fiat.  Defective battery.  Lack of internal resistance.  Not applicable in the case of your waste type charging system.  Listen to Nate!

I put a Kuryakyn voltage meter on my bike(s) a while back because I like being able to see the charge at all times.  

They are a bit price though, and there are plenty of alternatives.

This one is about $8:

and here's an even smaller one for $6

I may get one and mount it over the battery, under the seat.

DMS-20PC-1-DCM,

Been using one, actually two, for many years without any issues. 

Very easy to read with my old eyes.

two wire or three wire?

two wire, neg goes to ground and the pos goes to a switched + circuit like on starter.

three wire i think two go directly to battery and the third goes to the starter switch as it's a built in relay.

Since the thread was already trending toward being jacked, I'll take advantage of that and mention my preferred voltage monitor.

I have always thoroughly disliked the addition of aftermarket supplemental gauges, indicators, etc. I think most are clunky and dorky looking and inconsistent with all but a Harley.

About ten years ago I came across an ebay listing for a single small LED which changed colors depending on the applied voltage. I ordered one back then and have equipped most of my bikes with one since. Unobtrusive, easy to install, accurate, and very reasonably priced.

MONTY59, For most accurate results, you should use a negative feed directly from battery, not a frame or engine point.

that is not the one i linked you to -- that has two rows of led numbers.. looks interesting though.  is one voltage and the other something else like RPM?

yep top row shows volts and bottom reads amps

well it will connected in the same basic manner, except the big wires go directly to the battery, but i have to assume one of them is for a switch.

Where would it pull RPM data from?

voltage and amps.  not rpm.
