I reversed the polarity while changing batteries in my transmitter, plugged it in backwards. turned the transmitter on before i caught the mistake. found the mistake now radio powers up but does not transmit. any ideas what i fried and if so how big of job is it to fix? thank you for any input..

Sorry, but we'd not know what the damage might be unless we can see the system. Please see the 'sticky' at the top of this forum to get the url for the return forms and procedures.

Reverse polarity could have caused minor or major damage...only an inspection will tell.

Sorry we couldn't give you good news.
