Thanks all for the tips and advice so far.
OK, dumb question No. 2: I am trying to detach the reg. rec. to check and pack the connector with dielectric grease. How do you disconnect? There seems to be a little tab, should this be pulled out first before sliding out the connector, or should it be pushed in or what? I am loathed to force it as I will no doubt snap something in the process.
Cheers.
