Why is my battery charger needle jumping?
Could be caused by trying to charge a large battery or bank of batteries on too low of a current setting or the battery may have a shorted cell. Try again with a higher current setting or have the battery checked or replaced.
What should I do if MY Volt gauge is too low?
After a jump start (which you should never need or do) you MUST put that battery on a charger for 12 – 24 hours. A battery that has gone dead twice for any reason is no good. Replace it with the right one, not one you think will work. 700 CCA is too low.
Is the Volt gauge on my truck 9 or 14?
Yes just like the previous gen trucks. The volts will read between 9 and 14 depending on the load. It automatically adjusts. If you look at the gauge there is top dead center line then a line to the left and right of that. I will operate anywhere in between those in normal operation. 9 is an issue, but >12.8 is just fine.
Why does the battery gauge go back to 12 volts?
When your gauge read ~12volts and a new battery it went back to 15 volts, the old battery was overloading the alternator with an internal short. At one time I had a battery short bring it down to 9 volts and the computer went nuts. The engine back fired I just made it to a battery shop.
What’s the voltage reading on my Street Glide?
I have a question just for my knowledge and maybe some others. I’ve noticed on my ’08 SG with 90,000+ miles now that the voltage meter at start up is around 14.5-14.7 volts. After riding some time on the freeway, it goes down to around 13 volts and then when I get off doing streets, it goes back up to 14.5-14.7 volts.
When does the amp gauge needle move to the +?
The amp gauge needle will move to the (+) when the generator output is recharging the battery. The amp gauge needle will move to the (-) when current is flowing out of the battery, such as when the generator output cannot keep up with the electrical load.
Why does the Volt gauge go up and down?
The voltage always fluctuates, goes up and down depending on how much current is being used by the accessories, and the engine rpm, the charge state of the battery, the ambient temperate, all affect the voltage. Fluctuation is normal, it’s like the stock market.

When does the AMP needle move on a car battery?
The amp gauge needle will move to the (-) when current is flowing out of the battery, such as when the generator output cannot keep up with the electrical load. An amp meter does not (as many car owners assume) tell you if the generator charging system is working properly.
