Hi Guys,

Planning to purchase an alternator, but not sure which one to choose.
There are number of suitable new units available on ebay from 90GBP to 170GBP including postage to Ireland.
Most expensive option would be from mr2-ben for 170GBP. I wouldn't mind paying that money if it really lasts.

The one I'm currently running started to emit a faint humming noise.
This one is an aftermarket unit I installed in 2016 and currently has 83.000km (51.000miles) in it. I purchased it for 100GBP four years ago. I think it's a good price to longevity ratio. Unfortunately I don't know what brand is it.
It has a Denso part number on it, but it's not a Denso unit.

I'm hoping to buy one as a backup in case the current one gives up the battle.
From 1st of January, customs will apply for stuff from the UK to Ireland, so I want to buy it before that.

Please share me your experience with aftermarket units.

Any input greatly appreciated!

Cheers

I bought one of these this year because I'm going to need more power.

Good one, thank you!

A member on imoc mentioned Paul (TCB) whom I totally forgot about.
He has a 120A version which I think I'll go with. Anything been top notch from Paul.

200A will be too much for me
I have a few extra devices (mirror heating, washer nozzle heating etc), but all combined doesn't exceed 20 - 25Amps.

Still, I save this, might need 200A in the future.

Your input is greatly appreciated, thank you!

Cheers

I haven't installed this alternator yet, so I cannot vouch for the quality or reliability of this model.

Hopefully it will serve you well!
The only thing I don't like with the one you linked is that they state "NipponDenso", but it's clearly not a Denso product. AFAIK ND is always printed on the rear cover for these Densos.
Which may not mean anything of course, my chepo unit still going after 51.000 miles.
I guess you need some luck with these

As read on the forums, some people had new units failed after 1500 miles...

The above is actually purchased from Paul, I already sent him a message asking about it.

1500 miles... I cover that in 4 weeks easily..so it's clearly not an option for me.

I contacted Toyota as I would have willing to pay maybe 300-350 for a genuine Denso, but its discontinued.

Cheers
