Tl1000r electrical issues

[GhostRider]

So bought a TL1000r couple of weeks ago, 2 days later try to start it up after work and it wouldn't fire up, had to get Tarmacsurfer to come rescue me giving me a jump start from his robin reliant

So anyway I figured it was simply a case of worn down battery, bought a Motobatt to replace it, fitted that in this Saturday just gone, have used the bike perhaps 5-6 times since then travelling 6-8 miles each time, finish work today and again will not start, it tries to turn over but seems just not enough to get it going. I tried bumping a few times then retried electric start and fortunately it fired up this time.

My limited knowledge suggests probably the Reg/Rec is fucked and so isnt recharging the battery whilst its in motion, either that or the Datatool alarm is sapping all power from the battery - though I'd be suprised if it could drain a brand new battery in 3 days.

Is there a simple way to test the Reg/Rec? What else could it be?

The cheaper the solution the better, this bike is rapidly turning into a blackhole for money, so I just want to get the issue sorted so I can sell it on, and since I will no doubt be making a loss when doing so, I've no interest in spending a lot of money sorting this problem out.

Cheers,

GhostRider

Could it be the sprag thingy? It firing up after you tried to bump it suggests something might have come unstuck and I've read the sprag thing can cause problems as it's related to the clutch/starter in some way.

V-twins have sprags...your bike is a v-twin?

Multi meter on the battery when its running and see if it goes to around 14v when revved, if it does then the reg/rec is ok, but something has to be really wrong for a mottbatt to go flat, so my moneys on the shitty alarm.

Also lulz @ robin reliant.

Assuming the battery being new isnt the cause
and as its a new to you machine.
I'd start by testing the stator first then the rectifier and
then when its running, the regulator to know if the battery is getting properly charged when running.
I reckon its a good idea to check these from time to time anyway
plus all related cables and connectors.

If they all check out OK, I'd get a meter set to read current and with the bike turned off, remove the battery positive lead and see how much, if any, current is flowing with or without the alarm connected.

I wouldnt want to see any more than say 100mA running through the alarm in its standby state.

If the battery looks OK but the starters lazy
its possible the starter brushes are worn or it has poor grounding
Dont know the TL personally but some bikes suffer from a poor grounding on the brush plate inside the motor.
Power gets down from the battery and in via the positive brush and through the armature and commutator OK but the negative brush often relies on physical contact from the brushplate to the starter body for a ground and any poor connection here can lead to arcing which develops a higher resistance as it worsens.
This can cause erratic starting.

Don't know much about them, but possibly follow all the wires back from the alarm, remove them from the original loom and solder the original loom wires back together and heat shrink, or chocolate box them... but pup will probably ostracize me now.

Checked voltage across battery before starting, was at 16-17v. Started up bike and revved up to 5k (kinda hard to rev it much further without really pissing off the neighbours as its a rather loud bike) and it didnt drop below 15v. I'm guessing this rules out reg/rec then?

[stu_m]

first thing to do is to put NEW plugs in

these bikes are notorious for fouling them and without decent new plugs you are pissing in the wind

also get another multimeter theres no way you can have 16-17v at the battery when its not running

also the charging system on these are shite and unless its been modified the volts will drop when you rev the bike

16-17V?
oooh! thats not right
As said, check your meter, it may just need a new battery
you dont want even 15V across the battery terminals
about 14-14.5v is normal when running.

Trying to think of a quick and dirty meter test here
You could try it on say a new 9V battery and if it doesnt read 9V as near as dammit, the meters at fault.
You may see 8.8 ish on a used 9v battery

PC power supplies come to mind, you'll get a pretty good 5v and 12v there but if you're not happy digging about in the guts of a PC, leave it alone.
I'm afraid that until you have a meter that can be relied on, testings off the menu.

While the Tl may be heavy on plugs it should still turn over the engine smartly on a good battery even if it doesnt start.
New plugs on a machine with unknown service history is a good idea, but I kind of doubt thats the cause of your problems

While I'm rantin on....

If you measure the voltage on a battery just off charge or on a bike just switched off, you'll normally get an artificially high reading
A healthy battery left overnight at room temperature should give about 12.65V
One thats getting bit tired may show say 12.45V like mine
As they get older, less.
These are 'no load' figures ie nothing connected to them to draw power

That sounds pretty dire
Dont know the TL myself so did a wee google search out of interest and found this.

Fuck me I wish I'd known about all these issues beforehand I'd have ran a fucking mile from buying it

68,000 miles on mine and the electrics have been fine.
