2009 Tiger 1050 Battery Drain Woes

Sorry to hear it, alarms are often blamed for battery drain, the other thing to check for is chafed insulating, check around the battery then go for the obvious where the wires go through the holes ie lamps etc

 

Other than as said the alarm (try disconnecting to check) it will require a lot of patient testing with a meter preferably with a beep tester to tell you where there is a short to earth.

 

When did the reg / rec get warm ? after it was switched off ?
If so sounds like a defective reg / rec, probably a failing internal component or connection, as these are not user repairable replacement is the only option.

A guide to testing the components is here, you may find it of use.

Seems to be consistently loosing its charge whether connected or not. These are small batteries and so even a good one will loose charge quicker than a car battery.
most people on here use this;-

or something like it.
9 times out of 10 its the battery. Seems like you need a battery tender or a new battery, even with a new battery you will need a tender to keep it tip top.
Then the regulator/rectifier.
Then the Stator.





You want to check your ground s to frame,and your connectors ,and wires for shorts, frays,etc.

 

Hello and welcome to the forum Scott.

 

Your initial description and subsequent battery replacement make me suspect a wiring issue creating a parasitic draw on the battery that is draining it.
Fuse box and multimeter time and not as scary as it sounds.
Watch

The idea is easily translated to the fewer circuits of a motorcycle. You can then eliminate everything healthy and hopefully identify the culprit circuit and/or component. If it all checks out then I would suspect the reg/rec which is warm with the engine running (ditching excess generated power) but should cool on switch off unless itself shorting out......and which would likely reveal itself as the problem circuit.

 

Reg / rec is described as getting warm with the bike is off whilst testing for current draw.

 

I read that as a bit ambiguous!

 

I hate electrical gremlins too because unless it’s sparking you can’t see them!

It is not impossible for the 2nd battery to be defective but you just need to test systematically as you seem to be doing. I have just seen you on the Tiger site and don’t dissent from the contributors there.

 

I agree with @Callumity a systematic approach will provide a better resolution to your problem, just for comparison my T300 lasts nearly 3 months before it needs the battery charging, even though the clock is on permenantly.

 

Scotty Dog. First welcome to the Family. I tend to go along the lines OldYam was suggesting rectifier component failure. Hope its not the CDI. But check you don't have a short there somewhere like a split wire tatty joint. And you do sometimes get a duff battery. Stick with it and you will get there.
Regards
Joe.

 

Your first battery was goosed, ok.
I think the second is being scrutinised perhaps too closely.
Do you have power where you keep the bike?
If so get an optimate and see how it goes from there.
