Help with No Start (does not turn over at all)

[jimmybell]

It's been sat for some time.

It would historically turn over with a tricke charge or jump pack, and run fine, but knowing the battery was on the way out it wont hold a great charge, so i bought a new one.

• fitted new battery. this was much harder than anticipated due to the difficulty of fitting the tie down clamp. i could have knocked any of the associated battery box connections (as tehre's a bunch of electrical/ecu stuff surrounding it?)
• it turned over once, but didn't start. it now wont turn over at all. doesn't even try.
• dash does not light up, only response to ignition is a whine at top/back of engine bay.
• hazards work, headlights do not. lock/unlock works.
• battery has good voltage, jump pack also doesn't help.

any idea what to check? i might try rebuilding the battery box from scratch, but i'm not sure how to successfully fit the tiedown bracket again. it may also be threaded, as that's why i struggled to get it back in in the first place (i don't think that was my doing..).

local garage is going to fail i think, they don't know clios. linked my rambling build thread message on the same topic:

Check connections, Cables, and Earth straps first.
It's odd that some lights work and others do not. A bump start would prove that it's the starter or a connection to it, but I don't think it is that.

Has it been left outside in the rain? Is there any moisture/damp/mould inside the car?

Yea there was some mould in the car, only on doorcards tho.

Sorta feels like a connection/fuse issue, given power to some stuff but not others. If i wasnt busy sorting a windscreen replacement on another car and a leaky bathroom id have time to work out how to test fuses lol
