Hi Mike,
=20
First, what winter?
Second, I might be interested in purchasing one or two of these relays, =
pending the responses from the genii, as I have a couple of =
applications for them on the BT7 and the MGs (e.g. driving/fog lamps)
=20
Best, Mirek

Subject: [Healeys] Lucas 6RA Relays
=20
One for the electrical geniuses.=20
As I sort my way through my boxes and boxes of electrical parts I keep =
coming across Lucas 6RA relays. These are the ones in the little steel =
box with the bracket on the back with 2 mounting holes.
Ignoring those with more than 4 terminals I must have at least 15 =
different Lucas part numbers for what appears to be the same relay.
All are 12 volt and all have 4 terminals=20
W1 & W2 which are the coil (winding) and C1 & C2 which are the contacts =
... like what get switched.
A couple are normally closed contracts (NC) but the vast majority are =
normally open (NO).
I have checked the continuity between the various terminals and in all =
cases the C terminals are isolated from the W terminals and all =
terminals are isolated from the steel enclosure.
I've opened a few up and, internally, as far as I can tell, they =
appear to be virtually identical.=20
So ... to my question ... why all the different part numbers, as I =
understand it these things are essentially an electrically operated =
switch, what can be so different between them that they need to have so =
many different part numbers?
Perhaps I should also mention that Lucas is very particular in requiring =
a specific part number for each application... what am I missing.
Please avoid comments referring to the long Canadian winter ... they =
make my wife angry ... she's a local and they get a bit sensitive when =
such is mentioned =F0=9F=98=8A
