Bat Lo?!
« on: February 16, 2021, 12:35:54 PM »
So the Bat Lo message popped up recently on my 800 xrx 2016, the next day the system went a bit haywire and engine management lights came on etc and turned off traction control.
I checked the battery with a multimeter and it it appeared to be not up to scratch so replaced the battery and additionally started using an Oxford Oximiser 900.
All seems ok except the Bat Lo message pops up occasionally?? Anyone know why this is happening, The battery seems fine.

Have you also checked your new battery with a multi-meter that the battery is actually being charged ... i.e approx. 14v when engine running.  :084:

Yes it seems to be charging and the warning does go after a while, these are the various readings I took during the test,  New battery figures on the right

13.09 ignition off   new: 12.22

12.09 ignition on             11.93

8.09 pos 8.49 upon starting   10.06

14.40 running charge          16.64

14.12 2/3k revs              17.52

Those numbers on the right when the engine's running are way too high. Looks like a dodgy regulator / rectifier. Get it checked or replaced.

Way too high. Needs checking out as it's probably killing your battery

It makes no difference, battery old or new, running voltage should be capped at about 14.3-14.5v tops by the regulator. Strange though that you did in fact have acceptable readings with the old battery ..... unless the R/R is in the early stages of failing and intermittent (which is what I had over nearly 6 months).

Also when running have a look at your headlights and see if you notice any pulsing.  :027:

Ok just did another test,  battery been on oximiser.
No headlight pulse but definitely something not right re running charge rate!

ignition off  latest 12.92

Ignition on 12.62

upon starting 10.92

 running charge 12.10

2/3k revs           12.11

Will have it looked at..
Is the rectifier easy to replace?

It is a fairly simple DIY task but can involve requiring a bit of patience and fiddling. :028:

Those figures indicat reg/rec failure

Those figures would indicate a failed Stator

Huge difference in your 2 sets of figures
