Trotsky Posted April 9, 2009 Share Posted April 9, 2009 I have had an Autocom system since last summer and have been using battery's but as i usually have music playing the battery's give up the ghost after only a few hours, I have tried cobbling it to a 12v plug in device but it doesnt want to play. should it be hard wired in to the car to work or do i have a faulty unit? where is it best to wire it to if making a more permenant job, cheers folks Trotsky N7 HPC Link to comment Share on other sites More sharing options...
rgrigsby Posted April 9, 2009 Share Posted April 9, 2009 It should be fine wired to the car, Autocom do a plug in lead for exactly that purpose. You'll want to stick it on a fused circuit that's switched by the ignition or even possibly have it`s own switch (I wired mine into the fan switch as i don`t have a fan!) as it`s handy to be able to turn it off sometimes.

Bricol Posted April 9, 2009 Share Posted April 9, 2009 I bought Autocoms lead, but fitted a cigarette lighter plug - means I can plug it in when I want it, remove it (completely from the car if I want) when I want, and use in other cars, lend it to mates with straight cut gboxes in Minis, etc. Bri Link to comment Share on other sites More sharing options...
Trotsky Posted April 10, 2009 Author Share Posted April 10, 2009 Hi Bricol, I tried fitting a cigarette type plug in ,spliced to the lead supplied by auto com but the unit is dead when i try that, works fine on battery tho, connection in unit seems sound.

Stationary M25 Traveller Posted April 10, 2009 Share Posted April 10, 2009 Have you got the polarity (+/-) correct ? Have you removed the PP3 battery plug from the Autocom when on 12V supply ? Link to comment Share on other sites More sharing options...

Blokko Posted April 12, 2009 Share Posted April 12, 2009 The next problem you may come across is electrical interference from the alternator / sparks. I’ve just got a bridge rectifier (and capacitor) and a ferrite ring from Maplins in an attempt to overcome a background noise that I was getting on my Autocom (interference was related to engine revs). Got to be worth a try @ less that a fiver. -----Steve - Orange and Black ex Academy - now looking at things from a slightly different perspective.
