What is this box attached to my regulator?

[Luis A.]

It's attached to where the harness connector normally goes and then the harness attaches to it instead of directly to the regulator.

This regulator was bad so I replaced it with another one but left the little box off. So far, nothing untoward has happened...

I suspect a relay of some type...??

Further Testing

Try a few things:

If you have a digital continuity tester, see if it measures continuity through the device in both directions. If there are diodes in there, it's possible that continuity would work in one direction, but not flipped. Diodes should prevent the small DC current generated by the tester from going through 'backwards'.

If that is indeed the case, I would suppose that the little box helps protect against a reverse-polarity condition?

I have one, it's a radio noise supressor.

Regulator

Noise suppressor it is. Most of the CSI/CSL coupes running D-jet had these installed from the factory. I haven't seen a non injected coupe with one installed. I removed mine from both cars & could not tell a difference.

I think they were done by the dealer or whomever installed the radio regardless of fuel delivery as it is an alternator issue, mine is a cs. You may also have one that attached to the distributor that looks like a condensor (on mine) and also one on the alternator (not on mine).

I was going to say coffee maker and look like a fool. Your knowledge saved me.

No in-depth knowledge here, I had asked the same question a few months ago about mine, otherwise I would go along with one of your suggestions :mrgreen:

Great info, thanks. That's interesting because this is a Euro CS that does not appear to have had a radio although it does have a retractable antenna on the left front fender that is now in use with a 'hidden radio'. Did cars ship with an antenna even if they had no radio?

 

[Stevehose]

I suppose anything's possible but for US models the dealers put the radios and antennae in at the customer's request. Europe may have been another scenario but I wouldn't think so.
