I would isolate a few of the items into their own fuses. This is because you are driving a few heavy duty motors and would want to protect from expensive damages.

You can find simple fuse holders like this from ebay: http://www.ebay.ca/sch/i.html?_nkw=fuse+holder+atc&_sacat=0&_odkw=fuse+holder&_osacat=0&_from=R40

The fuses for those holders can also be found on eBay, and your local automotive repair shop

Thanks. I acutally had ordered a fuse holder that would go directly off the battery at the moment. What rating / strength of fuse(s) would be appropriate (especially for the EZ B and motors, which are the biggest expenses in this build).

Here's what I do; As DJ said put in a few circuits. I like to put larger items like large motors and sensitive things like the EZ-B on their own circuit. I also group smaller stuff together. However the more things on a circuit, the harder it is to trouble shoot if the fuse blows.

Which brings us to the fuse; Once you know what your going to put on a circuit you need to measure the amps it pulls under full load. You'll need to get a Multi Volt tester that is able to measure amps also. Then learn how to use it. It's as simple as learning the settings on the tester for what you will use it for and the levels of current you need to test. For example when testing amperage you place the two leads in the circuit (just like the wire running from connection to connection) and turn on the device to as full of a load as you can. Watch the amp meter and it will read the amperage level. Put in a fuse just a little higher then the reading. Example: meter reads 1.7 amps, use a 2 amp fuse. I always use a Slow Blow type fuse because without getting too deep here it will take more stress or surge before it blows. It's a little more forgiving.

As far as EZ-B goes I learned that the more you have it do the bigger fuse it needed. I started running with a 2 amp slow blow just fine. When I started running an H-Bridge the fuse blew. That's good. I just stepped up the fuse size a smidgen. Again, this is where your Amp Meter will come in handy.

Hope this helps, Dave Schulpius

Thanks DJ and Dave it certainly helps me

Thanks, guys!
Excellent information here.

Glad to help. Odd though that this only showed up yesterday. I sent this post 4 weeks ago! "Such strange goings on" (quote from Young Frankenstein).
