If you have a Harbor Freight tool store near you they are giving away multimeters free with a coupon.

I would also get some heat shrink tubing, preferably the hot glue type about 5/16 ID or whatever fits over the mic cord. After you strip and tin the wires to go on the mic plug, put about 1 1/2" of heatshrink on the mic cable to act as a strain relief under the connector cable clamp.
Finally, a tool I already have... a cheap digital multimeter.

Here's what's on the way from AMAZON...

Heat gun

Glue lined shrink tube

Alligator clips

Weller WES51 soldering station (with extra tips)

So nice to see someone come in here, ask for help, and then dive in fingers first and try to fix it (And learn something useful) themselves..

Kudos sir.. You didn't resort to the usual "well, I'll just take it to a shop" routine.. Welcome to the "I dood it myself" club!
Is there such a thing as too many radios??
Transceivers, receivers, and SDR! Oh My!
