Main relay question

[rocco1]

Hi guys,as you are aware i am having problems with starting my car.I have located the main relay and about to order a new main relay,but before i do this, the relay thats already not working(we assume) is still making a clicking noise,but no hiss.Shall i order a new relay anyway or is there anyone kind enough in the Manchester area with a NA2 relay that they use as a spare for an emergency that i can try,before i order,thanks.

The other thing you could try is to open up your relay, and just re-solder each of the joints on the circuit board.

I am sure there is a proper way to do this cleaning the old joints, using new solder etc. etc, but all I did was touch each joint with the soldering iron, wait for the old solder to melt & move in to the next one.

This technique got my 100% not functioning Main Relay working perfectly for the week it took for a new one to arrive.

Did youre relay make a clicking noise when it broke down?

No, I cant say that it was.

I just noticed the lack of noise from the fuel pump priming.

Just wondering: as you are writing about testing with a Na2 relay, isn't the main relay the same for all years NSX??

There are two types. I believe the dbw models have a different relay.

This is basically correct-ish! :)

There are 2 different parts for DBW / non-DBW cars, but the main relay 'box' is the same, it is the mounting bracket which differs.

Will have a new main relay on Thursday,i hope!

What is DBW-non-DBW??
I tried looking up the part number and as far as I could find, the main relay numbers on a '91 Na1 and a '98 Na2 car are the same.

Just got me a new main relay as a spare, as they seen to fail on quite a lot of cars lately and this one was offered brand new with a bit of discount :rolleyes: Always handy to have one laying around as exchange item in case of a malfunction search ;)

Drive by wire and non-drive by wire.

As noted above, I believe the main relay unit is the same for both variants, however the mounting bracket attached to it isn't. Hence there are different Honda parts numbers (I think).
