Optima Plus 2 & Relay

[lawandorder]

You need to go back to basics, and look at a circuit with relays, isolated from source.

Well I think you need to explain a little further, anybody can say "that's not the problem", pity you can't explain what the problem actually is.

Can you actually explain what a relay isolated from source is please?

Can you also suggest a workable method of adding a power supply to solve the OP's problem?

Not saying you can't like, I have been in electronics for over 30 years but still learning every day so your help is appreciated.

i think we may be missing the op point plus its been solved

as i see it its not an overall current problem, just that th eoutput deosnt have enough current, either sourcing or sinking to run the realy the op had.

as noted choices are either a lower demand coil or a t relay.

Pretty much thats it as i see it.

I think you're right Redbull, the OP no longer has the problem and your two solutions would be ideal. I had mentioned in an earlier post that I didn't think another PSU was the solution because the OP had suggested that he was going to look at that solution and it would not (IMHO) be time well spent.

I have expanded on why an additonal power supply wouldn't help simply because people sometimes think that an additonal power supply is the solution to all voltage drop problems and have no regard for where in the "supply chain" the PSU is connected.
