Miniature waterproof voltmeter, small enough to mount anywhere.
The perfect way to keep an eye on your battery and charging system,
especially in combination with the new generation of ultra-small
batteries, such as the Anti-Gravity.
Wonderful batteries but quite sensitive to over and under voltage.
I use these voltmeters on all my own bikes!
3.50 – 30.0 Volt
40.3 x 15 x 18 mm
Switch on the ignion and you should see 12.4 to 12.9 volts if your
battery is in good shape. With the engine running the voltage should
go up to between 13.2 to 14.2 volts which will tell you the charging
system is in good working order.
