Lucas 6RA Relay

[eugeneb2015]

Hi 

I have a 1970 P5b with an 11AC Alternator and 4 terminal 4TR regulator, I think the 6RA or 3AW relay may be a bit suss so am trying to find  replacements, I have seen Lucas 6RAs on the net but none of them have mounting tabs on the end so the terminals point upwards, The SRB111 seems pretty common an will probably fit (it has the same terminals W1 and C1 etc) but am not sure what current rating I need?

Hi Eugene, Most of that series are 20 amp so you should be fine, you can (as long as the 6RA's are Lucas) by un-crimping the case where it holds the Tufnol swap the cases

Great Thanks

I might try and swap the cases!
