Electrics Companion (Practical Companions)

Simple explanation in easy to do terms

Perfect for in our camper, and as an intro to using 12v electrics. Found it very usefull. Would recommend, but remember this is very entry level.

Very good

For Beginners, no science, no complicated bits, just a 'quick-check' guide for when something goes wrong - for non-marine engineers it is either this or blind panic! Good 'starter' for encouraging newbies on to something a little more complex. Expensive at full price, though.
