Radio / electrical problem

[kmleong]

I left my H2 parked for 3 months with a battery tender hooked up (2 amp) When I went to start it the windshield wipers wouldn"t turn off. Found the thread on this forum and did the fix (water in module). Drove home from the shop and now the radio won't turn off after I take the key out of the ignition, the little battery light on the dash stays on as well. Disconnected the neg. terminal on the battery and reattached, no difference. It was getting dark so I unhooked the battery so that it wouldn't drain overnight and will start again tomorrow. Any suggestions on where to start? Thanks in advance for any help that you might give me.
