electrical power loss

Hi,
I am new to the forum and am hoping for some advice re a problem that is getting more frequent.
Car is a 2007 Fiat Panda 1.1 Active.
What happens is that when starting the car there is a brief cut in electrical power which means the clock resets, radio resets etc. Engine turns over and starts fine. Have cleaned up battery terminals, fuses etc but its getting worse.
Any thoughts please?

Re: electrical power loss

Morning,if the car is an '07 and especially if the battery is original i'd be looking at the battery,it's just about coping with the load being put on it,to confirm it go to a spares place and get them to do a load test on it,HTH.

Re: electrical power loss

Thanks both for your comments re the battery. Will get it checked. Would it start the car as well as it ever did if it was on its way out? Perhaps it is able to produce plenty of power to turn the engine over but has soime other fault in it that leads to a split second of no output whatsoever initially when the key is turned? Certainly seems to produce plenty of power as soon as the key turns.

Re: electrical power loss

The way modern cars are with canbus wiring they can control what circuit operates when,so when you try to start it the car optimizes the power available,but because the battery is weak the power drops below the threshold that the ecu needs to operate hence your fault.

Re: electrical power loss

Hi guys,

It's been a while but I hope you all good. Please help as I think my problem may have started this way too!!!

I've been losing battery power for some odd reason, I'm thinking that it's electronic but I've no damn idea anymore, I noticed when i drove with my lights on that it drains more often then the battery light started flickering thats when i changed the regulator on the alternator and the battery light remained off afterwards not sure if its the plug fitting behind the alternator that may be dusted or what as i drove today i can feel the current is draining as it swinged with difficulty when i got to work and the power steering went off, the battery light hasn't gone on though? Please help this is a huge issue. Not sure if my battery meesed up either as i put it in my other car and it ran up again. Before all this happened I had the same issue where there was just a sudden cut in power where the instrument lights go off and the clock resets. Can this be related?

Regards
Fellow Fiat owner Zubair
