Drew-Mini Posted May 25, 2020 Posted May 25, 2020 May be a dumb question, byt doea anyone know what the acceptable charging voltages are for a 600 srad? On idle mine is 14.3V and with the revs up it 12.8V Thank you in advance. Quote
Drew-Mini Posted May 25, 2020 Author Posted May 25, 2020 I do appolgise for spelling and typos, i have no sensation in my right thumb so always the wrong letter on my phone. Quote
Captn Posted May 25, 2020 Posted May 25, 2020 In theory it should be the reverse of that. Idle would be in the high 12's and revving it would be mid 14's, not to exceed 15. Lead acid battery? Do you have a way to measure DC amps? Quote

I have a multimeter but auto eleca isnt my striny point without guidence as to what to.set the meter to if that makes sence. Quote
Captn Posted May 25, 2020 Posted May 25, 2020 You need a meter that clamps around the battery positive cable that measures amperage one similar to this to collect amperage reading. Quote
Captn Posted May 25, 2020 Posted May 25, 2020 Is the battery older? Was it on a trickle charger prior to being used in the bike? Was its state of charge strong? Quote

Captn Posted May 25, 2020 Posted May 25, 2020 After a 12 hour float charge, load test the battery if possible to verify its load carrying capability. Re install in the bike. Start and idle engine. Measure and record DC voltage and DC amperage at idle. Measure and record DC voltage and DC amperage at 4500 rpm. You should see voltage increase from idle to 4500. Amperage should not increase much during this same test. Carb or fuel injection? Quote
davemfox Posted May 25, 2020 Posted May 25, 2020 (edited) From the 600SRAD manual... Dave Edited May 25, 2020 by davemfox typo 1 Quote
Drew-Mini Posted May 25, 2020 Author Posted May 25, 2020 thanks for the help guys, will do some more testing this evening and let you know the results, will also let you know what battery is on it as i can't remember. Quote
davemfox Posted May 25, 2020 Posted May 25, 2020 According to the manual it should be a FTX-9BS. So a decent YTX-9BS will do. Dave Quote
Drew-Mini Posted May 25, 2020 Author Posted May 25, 2020 Honestly cant remember, lol. @davecarawill know what battery it is got it off him. Quote

NorthernBloke Posted October 27, 2020 Posted October 27, 2020 Not sure if it’s relevant but Tl1000’s have a similar issue where the charging voltage drops as revs increase. There is a wiring mode to fix it maybe Srads are the same, certainly the same era? Quote

If you are going to use a CLAMP METER for DC, Make sure it has a Hal sensor in the clamp. Old trans former type only measure AC ,one wire at a time only. Quote
