Battery Charger

[The Master Cylinder]

Most of the 6V batteries have caps that can be removed and check the fluid level and you can test the charge level with an instrument that measures the specific gravity. Can't remember the name of the instrument, but I have one.

Battery Hydrometer or Battery Specific Gravity Tester.

I have done this with the frequently "free" Harbor Freight Red Meters. They will measure up to 10amp DC and for about $6 (Pre-Biden Price) they give you a good "general" look at electrical condition.

Why do you have to make everything political?

I was just about to say EXACTLY what katy has said especially if they are GLASS which can turn.

Just because a fuse "looks OK" doesn't mean it is, it should be removed and tested to verify.

Many a lazy electrician has been fooled by testing fuses in the holders! remove the fuse a test. Cartridge fuses are the worst, pull the fuses and check for continuity !

I just reread the charger instructions and discovered I made a dumb mistake. They say to attach the cable to the battery and then plug in the charger. I did the opposite. Re-read the directions and did it right. They battery charges fine now. But, I discovered a new potential issue. My car has an alternator. I have a feeling that may be another problem. I'm thinking about swapping it out for a generator. As far as I know, all Model A's were originally built with a generator. But, I know people do the opposite and install an alternator. So, which works best?

I have bad luck with batteries after adding a bit of distilled water.
