i have up graded the stereo in my tractor and i have a problem the safety systems with in the tractor shuts down all electrical earths 6 mins after the key is turned off so the radios memory goes blank we have tryed to put a bypass power feed from the tractors battery but the system does not accept this and wont let the safety systems shut down so this drains the battery and causes other problems .
What i am looking to do is build a battery back up system that will switch over and save the memory but also recharge when the ignition is on so it is self supporting
From the research i have done the radio draws between 7 and 30 mill amp and i would like to have a system that lasts as long as possible due to machine standing for extended times any help you can give me would be great
