Paul H Posted January 2, 2018 Report Share Posted January 2, 2018 Still in the planning stage for upgrading the fuse box on my Mk 2 Vitesse to a more modern set up .The overdrive relay - see pic takes up a lot of room - If I need the space can I change the relay to the modern cube style ?

JohnD Posted January 2, 2018 Report Share Posted January 2, 2018 Yes, but check that it will take the initial current - 30A IIRC. JOhn Link to comment Share on other sites More sharing options...
Guest Posted January 2, 2018 Report Share Posted January 2, 2018 Paul. Further to John's reply, the relay does not need to be in that location - you can reposition it accordingly. If you intend to do a fair bit of rewiring, I would suggest using thin wall wire - it is thinner and yet carries a higher amp load compared to the standard wire you normally see in classic vehicles. Looking at your fuse box it is a mix of modern, old style and other connectors. IIRC via a previous thread, you are looking to change the fuse box set-up ?? If so, you may want to consider using only one type of spade connector if only for cosmetic reasons and originality - if so the classic spade connector with the separate clear plastic sleeve is the way to go. It makes for a neat finish and I believe that the wire connection is more secure with the overlapping lugs on the spade rather than the modern crimping style type - I would also say the same for bullet connectors. Just my opinion. Regards. Richard. Link to comment Share on other sites More sharing options...

Paul H Posted January 2, 2018 Author Report Share Posted January 2, 2018 There was me thinking it was a type of relay ? Paul Link to comment Share on other sites More sharing options...
Guest Posted January 2, 2018 Report Share Posted January 2, 2018 Paul. TBH, I would stick with the 6RA relay you have in the photo; albeit a new one. You are not going to gain much space by going for a modern square relay; swings and roundabouts I guess. Cannot be 100% certain but I think you will need a standard 5 terminal crossover (changeover) relay, which as mentioned earlier needs to be rated at 30A for the initial draw. Regards. Richard.

I will relocate to gain some space. The relay is just 18 months old Paul Link to comment Share on other sites More sharing options...
Pete Lewis Posted January 3, 2018 Report Share Posted January 3, 2018 Mine was fitted on the inside of the baulkhead, no idea why, it had OD as a factory option from new in 64. the D type OD solenoid takes an intitial current pull of 10amp which if the solenoid is working correctly will reduce to a continuous 0.5 amps when its engaged , so when you flick the switch theres a good current spike for a few seconds.

Pete Hi Pete , thanks for that. I will try to keep the relay in the engine bay for accessibility . The audible clicking I can hear on flicking the column stick is that from the relay or solenoid or both ? Paul Link to comment Share on other sites More sharing options...
JohnD Posted January 3, 2018 Report Share Posted January 3, 2018 Thanks, Richard, sorry Paul, IIRC is such a standard online acronym, I didn't consider that it would look like a special relay! And Paul has revealed my recollection as faulty, so 10A it is! John Link to comment Share on other sites More sharing options...
Pete Lewis Posted January 3, 2018 Report Share Posted January 3, 2018 Think the 6RA has a 20amp switching capacity Pete Link to comment Share on other sites More sharing options...

Good question Paul, I'm inclined to think it is the relay located on the bulkhead as it is a lot closer to the ear in the driving position. Regards. Richard.

Guest Posted January 3, 2018 Report Share Posted January 3, 2018 If you do need to change the relay at any point, Paul, then this is the part number: 142169A - not all 6RA relays are the same. Regards. Richard. Link to comment Share on other sites More sharing options...
Pete Lewis Posted January 3, 2018 Report Share Posted January 3, 2018 Dtype od must have a relay to pretect the column/or gear lever switch, wiring and switchgear D types does take 10 amp to get the initial solendoid pull in there is a button switch in the end of the solenoid Which cuts this to 0.5 amp when the sol gets to the end of its stroke A J type OD does not need a relay it only used 0.5 amp there is no pull in coil to load the current required That why you need a relay those reassuring clicks are your safety net.
