v70 2005 flickery lights and dash

[chefshoes]

so for a month-ish now the headlights and dash randomly dim in as if it was having a spasm and its not consistent but is worrying.

depending on who you ask its either the alternator on its way out, battery failing or both!

based on your collective experiences what is likely to be the cause as im about to buy a multimeter today to see if i can self diagnose and save a bit of cash.

thanks

My car had the same symptoms and were caused by a faulty aftermarket alternator that had been fitted to the car a few months before I bought it. If your car still has the original Volvo alternator you can exchange it for a rebuilt one for around £110-£130. Multimeter won’t show any anomalies

ill have a look to see if the one on mine is branded but thank you

mind at ease more than if i took it to halfords to check

Does the speedo and tack have chrome rings? Chrome rings means you have the new design.
The older design has "built in" weaknesses. These weaknesses include dropping out and flickering etc. due to bad soldering joints.
I do think you're on the right track because a bad regulator is so often associated with flickering.

Another thing you may already know is having your Volvo rebuilt by a reputable shop is better than a half-baked rebuild from some other supplier.

report from garage

dead battery
also noticed some loom damage

replacing as we speak

wont say how much it is or youll all tell me off for saying HOW MUCH!

get it done one less thing to worry about

[chefshoes]

battery replaced
no more flicker
but
no high beams anymore

when the weather is a bit less deluge-y i will check the fuses but suspect the stalk has given up the ghost.

unless you guys have other ideas/suggestions?

pull the stalk back not even a light on the dash and i cant flash anyone

in the summer not an issue dont really need lights till late but now theyre quite important

ive got dipped beams so can use it but no beams

[chefshoes]

i lied

flickers and engine seems to drop a few notes when it happens and it happens when the engine is cold.

odd AF
must be weird for cars in front thinking im flashing very badly!
