Sterling Power Alternator Protection Device for 12 Volt Alternator | APD12Sterling Power Alternator Protection Device 12v The most common way alternators are destroyed in the marine world is when a cable breaks, a fuse blows, or when an engine is electrically switched off. When these things happen, an alternator becomes disconnected from the battery. Resulting in a massive spike in the alternator, which can, in turn, easily damage the alternator regulator and any other advanced regulators being used, with resulting bills

Does the job, easy use, a bit bulky not exactly as described
Size: 12 Pairs / 24 pcs
Bare wire can be intolerable to work with. Banana plugs make a positive secure connection. These plugs are a touch bulky. Nice to not have to deal with small screws. Use as large of gauge wire as possible. The description says no unintentional disconnections. I beg to differ the bite of teeth aren’t as good as described. Used a 16 gauge pure copper speaker wire and a teenager taught me how secure the wire really is by tugging on the wire not the banana plug pulling the wire free. It does the job, it’s not the latest and greatest. If you need easy get these. If you want slim secure banana plugs buy the small screw type.

GET THEM!!
Size: 12 Pairs / 24 pcs, Size: 12 Pairs / 24 pcs
Fully gold plated inside and out! I initially got the amazon basic connectors for the same price, but was disappointed in the tiny burgundy positive label they had. It was also very dirty inside the connector and it wasn’t gold plated through out the connector. These are excellent in quality and have a bright red ban on the connector! You wont be disappointed and beats out Sewell connectors for the price!

Decent, but be careful of frequent use.
Size: 12 Pairs / 24 pcs, Size: 12 Pairs / 24 pcs
The looks are very nice, functional if left alone once assembled. After that I would leave them alone otherwise you risk the main male portion just coming loose of the housing, sound quality is decent, nothing to write home about, but again, not very durable. If they could fix that 1 thing, these would be very good buy and value, the rest of each plug is hefty and well made.
