Is there a relay controlling the start and charge system on octy 1. I am waiting on alternator lead to replace current one but if theres a relay for it I will change that as well. She has done alot of miles and wouldn't be surprised if could do with changing a few electricals

There's no charge or start relay

yes this is the relay...I changed mine 2 years ago.You can buy it only aftermarket and only by alternator code

You can see the carbon a bit worn.Before I change it the max charge to the batt was 13.7V and 13.3V in full load ,not I get 14.2V and 13.9V in full load

You are very wrong!

Where exactly is the relay?

on the back of the alternator,under the black plastic cover.

that isn't a relay,it is the alternators voltage regulator an electronic device which regulates the output of the alternator at 13.8 VDC.

Read the first post,this is exactly what trips wants,a relay(device,regulator....etc) wich controlls the charging.This is it!!It's a relay and charge regulator.

And I don't see the point arguing about the translation terms.

In my language this is official called

" releu incarcare alternator "

I.............I...............I

relay charging alternator

I repeat...

The ignition switch on a mk1 carries the full current for the starter solenoid and does not require a Terminal 50 relay. This is not true for other VAG cars that have a low current ignition switch. This indirectly provides data signals to the central electronics unit which switches a Terminal 50 relay.

There is no external relay for the alternator, there is no relay in the alternator and nothing that performs the function of a relay. Many, many year ago alternators required a cutoff relay (also known as a Terminal 51 relay) which may have been internal or external. This configuration has long been replaced by solid state regulators. This is what is shown in the picture - there are no contacts inside.

To be fair to IulianE, there may be a terminology/language issue here, as the word relay may be used in a wider sense (i.e. to pass something along). This may explain why 'releu' is still used.

When I say 'relay', I mean an electromechical switch.

When I say 'solid state relay', I mean an semiconductor switch.

When I say 'relay pump' I mean a pump that passes fluid along.
