Hi people, I have the same problem with the power steering light on and off but the battery light is always off. Somethimes the ABS and yellow triangle are on along with the message "fuel cut off unavailable".
I checked the alternator today and it outputs 14.16 V. The battery has 12.02 V when engine is off but the internal resistance is quite high. The electrician said that is still good but is worn out.
Do you think this is the problem? Thank you
 
Hi and welcome 66,

you have to check the battery voltage in running condition: while driving the car !
The voltage probably drops to power steering/ABS low voltage detection threshold. This is due to your weak battery not being able to provide all the requested power, so the alternator is the only provider, which leads to a lower voltage delivered...

I bet a new battery will cure your problem.

BRs, Bernie
