I have a sd-70 Lionel Maersk locomotive.
Upgraded to tmcc and rs.
Didn’t check as was before upgrade,but now headlights and taillights are constant on in any direction of movement ,any suggestions.

The cab and frame connect electrically for lights on a spring loaded contact block that is very finicky. Remove the cab screws, slightly raise the cab and then reach between with plastic tool to pivot that block slightly. Set cab down, power and recheck. It's trial and error. You might be able to reach down from the rear hatch on this model also. It takes some patience but you will get it.

Thank you, I saw those 4 springs and board.
Could you post the model number? I'm wondering if you have one of the "command ready" SD70s, or if you used the Electric RR TMCC/Railsounds kits.
Assuming the wire harnesses were not modified during the upgrade the only other thing that comes to mind is setting the TMCC feature code; this setting configures the TMCC board functions to match the type (i.e. steam, diesel, electric) and features (i.e. smoke, cab light) on your locomotive. Code 8 would be the most appropriate for your locomotive.

Hope this helps!

Sure and thank you!

here is the link.
You could just drop in an R2LC and that would have been TMCC enabled.
The contact pad looks like this. A hole is drilled eccentric intentionally. The spring contact block pivot eccentrically on the cab post and the contact pad moved eccentrically about mounting hole. Only adjust the one that was moved. Typically that is the spring block on within the cab.

The spring block in the cab shouldn't rotate around the post. It has a keying slot with a matching ridge on the shell post to keep it aligned.

I said in my 1st post, I've upgraded to tmcc and rs
Oops! I’ve seen those spring blocks turn before so maybe the index/slot was compromised. Based on John’s advice then only adjust the flat contact block. When a single spring touches 2 pads is when atypical light operation occurs.
I saw mention of a cruise commander, obviously that was not in the picture.
