Hello...I have a question. This weekend, my son installed a new Clarion stereo. It's the newest model with all the bells and whistles. When he turns on his turn signals,the radio goes off. The previous stereo was a Clarion also, but this never happened. The wiring system in this car is absolute stock.Never hacked into anywhere.We used the factory pigtail for the stock radio for power. We run a new 75 amp alternator and a group 24F battery. (motorcraft) Could the problem be solved by using a bigger Optimum battery with more amp capacity? None of the fuses ever blow, the radio just cuts out, turn off the blinkers,radio comes back on. Seems kids like stereos more than the hot rod aspect now adays. I was the other way around. Old school...Any ideas would be appreciated.Also if anyone is interested..I currently have a brand new,NOS factory scissor jack on ebay right now. Type part # D4ZZ-17080-A into search and check it out.It may possibly be the last NOS factory jack in existence..Thanks,Garry
If the radio has that large of an amp draw that you'd have to replace the battery (?), you'd have bigger problems on your hands (did you install fuses?). I would think that it's something to do with the wiring that was done to connect it, if the old radio worked fine, then something isn't hooked up properly, maybe a ground??? Plus, theres still alot of NOS parts in existence...
sounds like a ground problem to me. I actually had that exacly same problem on a Maverick years and years ago. my problem was intermitent and drove me crazy. turned out to be a ground wire problem. With them metal dashes in our cars sometimes the radio/stereo will ground it's self throught the case. Just check all your ground wires and also make sure the hot wire going to the stereo has a good tight connection
also you MAY want to consider running new heavier gauge wiring to your headunit. New headunits use a lot more power (i think) and although I havent had a problem YET. It is never a bad idea. If you wanted to go all out on the wiring you could use a couple relays to switch the radio on and off and keep the current on your battery and not your ignition switch and the likes. And one last thing.If you do infact decide to do this. Or if you need to re do your ground. Dont ground to the firewall as your are likely to pick up some noise from the engine. Just my two cents
the don't ground to the firewall is an excellent suggestion. I try not to ground to anything under the dash and beleive it or not that was a specific instruction on the install procedures for the Tach I just put in my 73 grabber. It specifically said something to the affect that while you can get a good ground to anything metal do NOT ground the tach to anything under the dashboard as it would interfere with its accuracy and give incorrect readings or intermittent problems or some such mess.
