I just replaced the 2 solenoids on my 1980 rinkerbuilt Mercruiser 470 trim pump with 2 new solenoids from autozone,my problem is the boat was running before and now I hooked everything back up and turn the key and get nothing....not a gauge moves ,absolutely nothing.is there something different you have to do when using automotive solenoids on the trim pump?thank you for your help!!!!
