CB= Too Much Draw For Batteries???
I just finished installing my Cobra 29 on my truck & now I've got some sort of a surge problem. I originally wired the CB directly to the driver's batt.(the CB itself, has an inline fuse). I started the truck up & let it run for awhile as I haven't driven it in about a month. Now, when I turned the radio on, nothing seemed to be wrong. But when I keyed the mic, the idle of the truck had dropped like the battery was draining. Just for shiggles, I took the (-) & hooked it up to the (-) on the pass batt & I get the same thing, maybe a hair better.
I hooked up my multimeter to see what I was getting for voltage. @ idle, the batts. bounce around between 13.6 & 13.58 with the radio on or off. When I keyed in the mic, it drops to about 13.4-13.44 & won't climb any higher until I release the mic. The batts. are relatively new Optima Yellow Tops & the CB itself is just a regular ham radio with no modifications.
I've had CBs hooked up to past gasser trucks with single batts & never had this problem. I don't get the alt. light & the dummy needle doesn't move when I key the mic. Is this plain-jane radio really drawing this much voltage, or is there something else I need to check? How about better suggestions for (+)/(-) hook-ups? Anyone else ever have this problem?
