That cap should be OK.

The main thing is the lead spacing.  Will look that up....


Capacitor, electrolytic, Polarized, 1800uF 200V, THH Package Dia 35mm LS 10mm

SO the lead spacing is 10 mm   

That's  0.39   inches  which is not usually  specified in inches as far as I know.

Update: the parts have arrived, but I ran into an issue last night with my soldering iron. Not enough power to remove the parts, esp the capacitors. Going to try source a more powerful one with a wider tip today..

I do not see your soldering iron but this power board is a 4 layer 4 ounce copper board that requires a big tip as well as more than 100 watt iron.   I use a 200 watt iron for any work on the through-hole components on this power board.

Good luck !  Keep us posted.

Sigh .... the capacitors are not the right size, don't think this will clear the enclosure.  >:(  >:(  >:(

At this point .. I feel to just give up and tell her to buy a board.....

Let me clear my head and re-evaluate .. what to do next.

Is it possible to extend the leads on capacitors, put some insulation on them, and lay them at and angle or sideways so they fit ? Not sure if that is okay electronically or not but I just watched a video of Mr Carlson doing that on a repair-  though it was just on a small speaker capacitor.

Hi @ClassicCrazy and folks.

Just spoke to the nice couple who own this Charge Controller. They have elected to replace the power board going forward.

Can you confirm that it is the 13-003-1 model number that we are to order ? (its a Classic 150 SL)

You should contact Midnite directly about that.

I suspect from the photo, the new capacitors are LONGER than the original  ones.

Yeah Mike, that is the problem indeed. The couple has decided to just buy a new board from MS or their Amazon store.
