This was what happened to mine. It took a few resets before it eventually came good.

How would you recommend testing the discharge of the cap? Where is it located? I have a multimetre laying around should do it eh?

It’s not a thing as such. Discharging capacitors is what it is. Capacitors store charge for certain functions of various components and modules. They are part of the circuit boards.

To reset (for want of a better term) things, we can’t just disconnect the battery or pull a fuse. The capacitors act like a short term battery.

A straight forward method is to disconnect the negative terminal. Then start the car, open the doors, turn on fans, press the horn, unlock the car, turn on the headlights, interior lights, change the gears. Hazards, indicators, Just operate everything you can without having the battery connected.

More important still is to check all the plugs. Imagine a TV not working. It’s going on and off. Overthinking things and replacing components but it still goes on and off. Then someone says, it’s not plugged in properly. Make sure all connections are good.

Then switch everything to off. Close the doors etc. reconnect the battery negative.

This will cost nothing to do other than a bit of your time, which is cheaper than wasting someone else’s time and you paying for it.

Use the maximum CCA you can get in there. Always.

Maybe its a crap battery? Or under powered?

New battery just a few months old

New battery just a few months old

How many cca?

 

[Stuart Crosby]

I’d be checking over the plugs and connections behind.

Do a capacitor discharge and see if that helps. (Costs nothing)

So just remove battery power for a while and then reconnect

How many cca?

Off hand I think 590cca
