Hi, I finally was able to make my own jumper wires and successfully test my blower motor and fan motor; however, I have some questions now:
1) When I went to jumper my blower motor to my battery, I only needed one wire from the positive prong of the motor to the battery, even though there is a negative wire coming from the wire cluster to the motor, which attaches to a bolted on prong on the blower motor body. Why do they have both a positive and negative wire for the blower motor if you only need the positive to run the motor?2) I need a way to securely attached a jumper wire to a female electrical connector, where the terminals are recessed, and there may be a lot of free space around them (so any test lead will not stay put while you move your body elsewhere).
Right now, I use alligator clips to connect to regular prongs/plugs (like on my blower motor) and paper clips to connect the terminals of a male electrical connectors (you just plug in the paper clip next to the terminal, and it stays put).
3) If I am using 20-gauge test lead wire right now from Radio Shack as jumper wire, will this gauge be thick enough to safely test motors like fan motors? I have a spool of 14-gauge thin stranded wire from Lowe's, but this is not that flexible. Radio Shack recommends 10-gauge wire for automotive uses though.4) Is an inline fuse really necessary for jumper wires? You can get them at Radio Shack, but they are expensive.
Thanks for any help!
