Laser Battery / Alternator Tester
what a gadget
Very easy to use tool to check voltage and alternator state on vehicles.
Light system very good idea even for a novice to use.
Small size tool is ideal to get in tight spots to check alternators and you can always see what's happening with the lights even if your under the bonnet!
A very handy piece of kit, that's not expensive, does the job. And isn't as complicated to apprentices as a multi meter !

very helpful tool
this is so quick and simple to use and doesnt need a battery and can be slipped into the pocket
the bottom three lights tell you the condition of the battery and the top three the state of the alternator
as well as using them as a hand tester
i fit them permanently to caravan or narrowboat 12 volt circuits - you can see at a glance at all times the state of your battery and if charging batteries you can see how the alternator is doing
really really useful - even though I can use a normal digital multitester...
