Perplexing electricity

Howie666 · 26th February 2021, 16:19

Hello from Preston,
I am perplexed at the Raptor. She has had a new battery (spiffy Bosch job) and a refurbished alternator. When I have the aircon on, I press the accelerator pedal and the fan speeds up. When the aircon is on and I indicate left or right, the bulb warning lamp lights up.
Please can anyone help?
As always, any advice welcomed,
All the best,
Dale

Hello Dale,

Regarding the heater blower speeding up, activate the instrument pack diagnostics and select test 9.0. This will display the alternator charging voltage. What does it read at idle and when you press the accelerator?

Do you mean the bulb failure warning lamp? Are you saying that when the air conditioning isn't active, this warning lamp doesn't illuminate?

Hello Simon,

First, thank you for your advice, I will run the test you mention. Secondly, yes, when the aircon is on and I indicate left or right, the bulb failure warning light comes on. When I cancel the indicator or turn off the aircon, the bulb failure warning light turns off.

Hi Dale,

Thanks for confirming. Whilst the involvement of the air con. might mean a k-bus problem, the first thing I would do is check visually the indicator lenses to see if there is, in fact, a blown bulb. Or have you done that already?

Yes, I checked the indicators. They're all working, but way too fast! Ah, the joys of elderly car ownership ��

Generally when the indicators flash fast, it's due to a dodgy bulb, regardless of the age of a car. The system does activate when there is a poor connection too.

Hi mate, just start the engine as normal, then go through the procedure on the obd 😎

Holy thread revival Batman!

So I finally got the obd dongle to work. The voltage reads 14/14.2 with the engine running. Switching on the aircon drops it to 13.4ish. Turning the hazard lights on drops it to 13.1, and the bulb failure warning light turns on. I'm guessing it means there is a fault but I don't know where.
Any advice please!
All the best,
Dale

Just a quick bump, I'm still having trouble with the Raptor ��

Hi Dale,

I suspect that the regulator in your refurbished alternator is faulty.
