I have a 1948 8n 12 volt conversion, running fine for a day and the next day it won't even turn over. When I press the starter button it just clicks
down inside the starter. Any ideas, thx in advance.
 

discharged battery would be my first suspect, from there i'd start checking for loose and/or dirty cable connections.
 
Craig......tip: yer BIG 3-terminal 6-volt starter solenoid works just fine on 12-volts. Same with yer 6-volt starter motor. Me? I'd pull the two 8-in starter screws and starter motor out about 1/2-in and sandpaper both sides of the gap fer better electrical contact. Putter back together and be amazed at the whurr-whurr of the starter motor 'stedda the rumpa-rumpa. Oh yeah, points (0.015) and condenser don't care, 6-or-12 volts. Ennytime, you have starting difficulties, change yer FLOODED sparkies. Recommend AutoLite 437's gapped 0.025. Don't throw yer FLOODED sparkies away, just clean'n'dry 'em, one-atta-time in HOT running engine and save'um fer the next time. (and there will be a NEXT time) Final comment, sometimes the battery clamps gitt corroded INSIDE the insulation. Only cure is NEW cable. ($5, cheap)........HTH, the amazed electrical Dell and self-appointed sparkie-meister
 
The solenoid is making a noise because of low voltage. That is likely caused
by:

1. A weak battery (charge it & check it per tip # 49. Or get it load
tested.)*

2. Dirty grounds/connections (remove the cables & clean the connections)

3. Bad cables or incorrect sized cables (replace them - see tip # 41)**

4. Bad ground between the starter & the block. (pull the starter away from the block & clean the mating area - see tip # 36)


* No matter what else you do, the battery must be fully charged. A float charger is helpful; not a trickle charger, but a float charger. (I use Battery Tenders on all my tractors) If you need to jump it, see tip # 43.

** You can't see corrosion under the insulation.

If you get one click each time you press the starter button, it could be a problem with, 1) the solenoid contacts- not making contact, 2) the starter - brushes etc. not making contact or 3) the ground connection between the starter housing and tractor bell housing - clean mating surfaces.
 
Thanks for the advice. I will try and clean the starter mating surface. When I press the starter down it continues to click click click as long as the
starter button is held down. I will also make sure that the battery is fully charged. Thx again!

Click, click, click, typically results when the current draw from the starter reduces the voltage at the solenoid to a very low value, causing the solenoid to open. Since there is no current draw when the solenoid opens, the voltage returns and the cycle repeats. This suggests a weak battery or faulty connections between the solenoid and the battery.

Cleaning the starter mating surface is good maintence practice. But, the click click cycle suggests the problem is elsewhere.

Post like this make me glad I can fix my own chit and don't depend on being mislead down a ruff and rocky road...
