Kenwood th - 79E playing up

I got this kenwood, it worked for a while then suddenly stopped, so i put in the charger and turned it on, didnt power up, so i tested the voltage on the battery, 4.6v, put the battery in and put the charger in, waited 10 minutes, took out the battery, tested it again and it was 4.55v, lower than before and still doesnt fire up.

what is my problem?

I had this problem too and found that the d.c. in/charge socket on side of radio had failed , got a replacement from Kenwood and fitted it myself (not an easy job)miniature bit soldering iron and magnifying aid needed.When rebuilt the radio seemed to be perfect and working like new,but the replacement socket was not the same as original and did not allow safe charging of the battpack unless SUPPLIED CHARGER ONLY used or battery will overheat or worse if 12 volts is used.................. TRY charging the battery away from the radio using a different charger with crocodile clips or similar lash- up for a few minutes 4.8 volt battery six volt charger
6 volt battery 7 volt charger and so on, then if the radio powers up
after the battery is refitted HAPPY DAYS Before you do all this check your charger output plug with a voltmeter GOOD LUCK

Charger should be able to power the radio at 'EL' level, if NOTHNG happens, I'd say charger is on the blink.

Kenwood 79a dual band transiever


There are several reasons for this, but one can be the flex that joins the display with the circuitry, carefully check if this is not broken or in this process or dirt.
