Not a high stakes problem but its got me stumped.
12V DC
12v fused (3A) from engine battery (on constant trickle charge from pv cell) showing 12.9V
Live to bilge pump via float switch (tested several times) working fine.
Earthed direct back to battery for the moment.
Bilge pump when connected direct to pos and earth runs fine, pumps strongly.
When switched on via float switch it runs not and just makes a slight buzzing noise. Volt meter from pos out float (to motor) and neg out from motor when float switch in on position reads 0.8V
Leave voltmeter clips attached to terminals and remove motor from loop reading is 12.9V
Im giving up and going for a gin in the garden
