Ingah Posted September 21, 2011 Share Posted September 21, 2011 Just a quickie - can anyone tell me if its safe to leave my bike's battery connected so I can use the alarm, having taken the regulator/rectifier out of the bike. The ignition switch is disconnected to prevent mishaps, but i'm just looking for reassurance i'm not going to burn my garage down overnight Quote Link to comment Share on other sites More sharing options...
fredc Posted September 21, 2011 Share Posted September 21, 2011 The alarm runs off the battery anyway and the regulator/rectifier don't do anything until the engine is running Quote Link to comment Share on other sites More sharing options...
Tango Posted September 21, 2011 Share Posted September 21, 2011 I think you should be ok there.......so long as there are no loose wires that could touch the frame. Quote Link to comment Share on other sites More sharing options...
Ingah Posted September 21, 2011 Author Share Posted September 21, 2011 Cheers guys, feel much better for leaving the alarm enabled Quote Link to comment Share on other sites More sharing options...
Colin the Bear Posted September 21, 2011 Share Posted September 21, 2011 When turning by means of the engine, the alternator generates alternating current (ac). The reg/rec rectifies this ac to direct current (dc) and regulates it to a suitable voltage for the bike's electrics, including the battery, to use. The battery is a handy store of this energy to utilise when the generator is not running. Using any of the electrical equipment on the bike with the engine not runing is similar to using any battery powered appliance.eg radio, torch, mobile phone. The battery will go flat over a period of time and need recharging is all that will happen. Quote Link to comment Share on other sites More sharing options...

Cheers, was aware of that, and it was precisely because i'm aware of the fact the reg/rect keeps the battery from being provided with too high a voltage that i was wary, because i'm not sure exactly where abouts in the electrical system the alarm connects to/with. The bit i was a little unsure of was if it also had the function of keeping the battery from frying other electrical components in the bike. Better safe than sorry, and didn't trust myself to read the wiring diagram correctly Quote Link to comment Share on other sites More sharing options...
Colin the Bear Posted September 22, 2011 Share Posted September 22, 2011 The battery won't fry anything. The battery is 12v dc and the components are designed to use 12v dc. The alternator can kick out up to 400v ac. Which the battery can't handle over a prolonged period.http://i195.photobucket.com/albums/z28/Colin_the_bear/food-smiley-013.gif Quote Link to comment Share on other sites More sharing options...
