Battery problem.


ricochet

Recommended Posts

the car had been unused for about a week , certainly no more than ten days but the battery was flat.

it did same thing a few months ago   so i turned the interior light  off in case there was a power drain.

Have the RAC sold me a battery thats not up to the job?   ( 2-3 yrs old)

WITH EVERYTHING TURNED OFF...…...

SET MILTIMETER TO 10A DC

Disconnect the negative lead.

One probe negative lead one probe battery negative,

Someone will be able to tell you the normal residual reading for alarm etc.

Do you have a Bluetooth dongle permanently in the OBD2 port?

I can't tell you the residual load, however my battery still started mine after a month of sitting; so one week is definitely unusual. Could be a residual load, could be the battery.

I have o throttle controller  SP1,  plugged into the diagnostic socket , it was therewhen i bought the car.

I bought a mini clamp meter  Uni T 210ut but i couldnt get any info from it , maybe i couldnt understand the instructions.

Battery prob,  will call out RAC i think, but if it is i wont have one of their batteries again.!

Probably, but it hasn't caused a problem before.

I am having a lesson in clamp meter use tomorrow.

all that support for a University education is about to pay off.:) 

 

only about 20mA drain at most,   deffo a poor RAC battery.

I'll call the RAC out and see what they have to say.
