Anyone have a Denso alternator to suit an 89 740 they are happy to sell?
Pretty sure the rectifier has failed, no charge and all warning lights on dash (except) oil pressure are missing pre-start. Only rectifier I can find is an aftermarket eBay option from the US, would prefer to swap in an OEM rectifier is they're available.
Seems the 89 has a single pulley unlike the 940's, unsure if they're interchangeable as I haven't had much to do with the Denso units.
Denso was only 92+
If you have one on a 89 someone did swapping unless it's a 16v and then volvo did do a few funny things
The rectifier is prob fine, just needs new brushes
Yes it's the 16V with the Denso. Reading some others people's dramas with the dash lights being out simultaneously with all warning lights missing on dash except oil (pre start) the issue turned out to be the rectifier. Either way, all components to repair these Denso units seem to be aftermarket of unknown origin/ brand etc, which is disappointing.
Only alternator failures I've ever had on the Bosch units were easily solved with a new genuine regulator/ brush assembly.
Rock Auto has what appears to be an entire unit of same type brand new from "WAI global".
I have an entire alt you can have for free if you can pick up from 2148
