Date Posted: Wed, Oct 09 2013, 12:29:35 GMT Recently my 582 engine has become difficult to start (it used to start first time everytime). New plugs, correctly gapped helped, but I was almost stranded at my recent visit to Pound Green. In the end I shut one of the plug gaps down to around 0.10" to get the engine to start. I think the problem may be caused by the battery getting a bit tired, not helped by it being much smaller than recommended (a Motobatt 5AH battery). Whilst it worked well for around 12 months it has had a hard life because I let it go flat a couple of times (left master switch on) and because my regulator (now replaced) would periodically try to stuff 17 volts into it). I did some checks yesterday and the engine started first time (the plug gaps were restored to normal). But with the mags turned off the battery voltage when the engine was cranking was just 10 volts (and virtually the same voltage across the starter motor). The engine was turning at 590 rpm true (shown as 650 rpm on my Avia rpm meter). Does anyone have any info on what the cranking voltage or RPM should be to ensure a reliable start? Many Thanks Bob [ Next Thread | Previous Thread | Next Message | Previous Message ] |
