grim32 Posted October 24, 2005 Share Posted October 24, 2005 hey guys, not a big deal but something i still would like to fix. just installed a new dvd player and moniter, when its all switched off you can hear the alternator whine through the headunit i think, but when switched on even with no volume it goes away. just wondering if you guys have any ideas, thanks.

Space Goat Posted November 2, 2005 Share Posted November 2, 2005 i know if you have the alternator whine coming through your amp you run the rca lead and the power lead down different sides of the car... but dont know how u could apply this to your problem... a little food for thought Link to comment https://www.sau.com.au/forums/topic/92293-funny-one/#findComment-1683647 Share on other sites More sharing options...
grim32 Posted November 2, 2005 Author Share Posted November 2, 2005 thanks for your response, it does seem like some sort of interfearence problem. havent rechecked anything yet but will do soon after it goes back on the dyno. it isnt a daily driver and i only play with it when i have nothing to do so im not in a big rush. thanks.

race_snooze Posted November 6, 2005 Share Posted November 6, 2005 get a new balist resistor for the back of you alternator its a little cylinder attached to it. Next bad earth somewhere (dirty) most likley your remote lead from head unit to amp. Next power cables to clost to speaker or rca leads. They pick up signals from power cables and play in the speakers Link to comment https://www.sau.com.au/forums/topic/92293-funny-one/#findComment-1694407 Share on other sites More sharing options...

unarmed_skyline Posted November 8, 2005 Share Posted November 8, 2005 if you havent had any problem's with whining in this car before and theres no-interferance anywhere from an outside source, its most likly a grounding problem as mentioned ealier, it could also be a power leak somewhere into either the ground loop or the 12+ loop, if re-grounding everything up mabye try running just one long wire from the gound of the dvd unit straight to the earth in the battery just temporaraly if the whine goes away its a problem with your ground loop, so try gorunding in a different spot or use a different route, if it still occurs it could be a 12+ problem which is more difficult to fix, if possible try a different power source, if all fail's find somone who has an ossiliscope thingy which meausers your power/ earth frequency's and try and source where the interfeerance is comming from, other than that mabye it is an alternator causeed problem, which i doubt if the sound does go away, another possibility is you may have your remote wire plugged (or any of the dvd wires) into the wrong spot and so it could cause some sort of feedback when the unit is off but then when it is turned this wire could react different with constant current running down it, i know i had this problem one time when i grouned a mates head unit up to what seemed to be an earth wire n turned out to be an accessory wire which stayed earth untill activated, if all fails try temporarly installing the dvd unit to an external sources (another car, or threw a computer -- or some sort of 12 power sorce) and make sure the gear isnt the problem Link to comment https://www.sau.com.au/forums/topic/92293-funny-one/#findComment-1698808 Share on other sites More sharing options...
