Having car batteries or alternators diagnosed and fixed can be unnecessarily expensive, both sit firmly in the realm of DIY. Replacing an alternator can cost up to $300, when in fact all that may need to be replaced is a $20 voltage regulator. This device will help you diagnose the source of your cars electrical problems and potentially save you a lot of money.

It simply plugs into your car's cigarette lighter socket and will present you with alternator and battery status. On the left side is the alternator status indicating if it's charging the battery at too high a voltage (red LED >14.8V), Normal (green LED 13.4-14.75V) or too low (yellow LED)

Alternator status:
• Red LED: Too high >14.8V
• Green LED: Normal 13.4-14.75V
• Yellow LED: Too low

Battery status:
• Green LED: Charged 12.4-12.6V
• Yellow LED: Recharge 11.8-12.35V
• Red LED: Dead
