Hi guys

Decided to get me an older CRV ahead of a new one next year. Have got a problem that the local garage is struggling with.

When driving last night, my satnav turned off completely and back on going back to the pin code screen, meanwhile the speedometer needle wouldnt move and the info on mpg gauge underneath went off.

The battery light came on along with the abs and vba light.

I parked up, turned off the engine, when trying to restart, car wouldnt kick in.

RAC came along and his on the spot thoughts were alternator. He followed me back to my local garage after charging the battery (he confirmed it wasnt holding charge). The car went fine for the 8 miles to the garage, although I did hear a sort of rattling/whining noise occasionally coming from the area of the timing belt/alternator.

Garage has phoned this morning, they are not sure its the alternator, they are suspecting its the battery or an earthing problem. Anyone come across this before?

cheers

It’s possibly caused by the voltage dropping to low, it could be just a poor connection but battery/alternator will be the first things to suspect, you don’t say what mileage it’s done.
If you have only bought it recently they may fit a new battery and alternator under warranty (if you got one when you bought it).

The above is not going to help with pointing you in the direction of the problem but hopefully it will be one of those two parts.

Take it to another garage without delay, as this one sounds like they have absolutely no clue about electrical problems.

Someone with a multimeter who understands car electrics would be able to assess battery condition, alternator performance and/or an earthing/connection problem within a few minutes.

Seriously!

Just wanted to mention, I have a 2006 cdti and it lost power like this, wouldnt start up. Took it to my local honda specialist. He told me there was a recall to reroute the alternator but the recall was only carried out on cars within certain dates. Long story short, he re-routed it and it was fine. Just sharing my experience..

My daughter's 2006 CRV 2.2 CTDI performed a similar trick last week. Cut out mid journey, lost speedo, lost radio, ABS light etc. would not restart. Left for an hour and reluctantly restarted once, but not a second time. Restarted with jump leads and drove 10 miles without problem for battery check. Turned out battery only half charged but in reasonable condition. Alternator was ok. Recharged using trickle charger and battery returned to good condition and run ok since. Radio needed code so power definitely lost.
Interesting posts re the recall and belt reroute. Will investigate further. She had no recall notice.
Battery and alternator checked with fancy motor factor machine and also with my multimeter and both registering healthy.

Mileage around 120k from memory.

Having personally 're-routed' my 2005 Accord using the shorter belt (1785mm = universal/Gates code 7PK1785) and removed the then redundant idler, I can't see how this might relate to an electrical problem. It merely results in less strain on the alternator bearing.
