Hi guys. Just wondering if anyone has the specs for the ignition relay that is located near the fuse box on the st4s? I am chasing a nausance earth fault and this may be the culprit!!
Superb I am now on the hunt for one of these relays!! is there any evidence that they could cause earth like issues with the dash, lights and temp gauge?They were made by German firm Siemens who were purchased by electronics giant Tyco who have since become TE
The original relays were Siemens part number V23073. This is discontinued for the V23074 which is 3m taller and wider but includes a resistor across the coil terminals to suppress negative drop out voltage spikes.
Also the original was a make and break circuit know as “form A”. (two terminals for the switching, two for the coil) Most relay companies stop making these now and offer the same relay as change over type known as “form C” (three terminals for switching - a common, a normally open and a normally closed). The duke can live with this new type as the fifth unused terminal socket is in place but just not needed.
So all relays on the ST can be changed for these new types
