JensR-thanks for the link-I read that and may give it a try. However,that doesn't make sense to me strictly from and electrical point of view and seems like a good way to ruin a radio but it is no good to me as it is. I already have the limit switches installed and the rocker switch will work the dump box but I still have to have an on-off switch for the lights. Live & learn I guess. I was trying to get by with a cheap radio and I suspect it is not going to work.
