Bloody hell! I've just managed to drag myself down to RS Components and get the resistors in question. Just wired them up and hey presto - still flashing like the clappers. Removed the resistors and they are slow and steady. Bloody nuisances. I think I'll start using hand signals instead!!
Guy is still ahving problems with his.It might be of interest to see if the year of manufacture has anything to do with it.Mine is a 95.No problems with the resistors!
.......mine flashed too fast, the I removed them, replaced them and after trying different combinations of wirings (are the indicators polarised?) I go them to work fine!!
Then one set started flashing quicker than the other side!!! I thought that this might be a loose connection, but all seemed fine!!
I've now taken them off the SPS and will be putting them on the R soon, so will try again.
Is it to do with wiring polarisation? Perhaps the front sets? Is there a wiring diagram that covers the correct wiring polarity for the indicators?
I think the answer is a"heavy-duty flasher relay". They provide a constant flash rate and are not sensitive to load changes. I've used them in the past and they work well. They are a form-fit-function replacement for the OEM relay. Not sure where you get them as they don't seem to available in this country upon a cursory check. I now you can get them int he states at any auto parts store.
