Ok it nothing to do with motorhomes my boat but I replaced the solinoids on the starterwmotors what I thought was like for like brand new out the box
When I connected up thay don't work two brand new batteries power getting to them.
But thay don't energise.
Engage the arm I can't work it out
Not verry often I am stumped
Engines are x2 FORD D4 diesel engine
Missing sumthing sumwhare or I have been supplied 24v instead of 12v

Also do you still have the old ones to just try alls good.

You could link the batteries to make 24v by using jump leads and try a starter?
 
Check the neg to block/s motor. Bad neg is same as a low power

Check the resistance values of the coils in the old ones and compare them to the new, that should let you know if they've sent the right voltage units ?
 
If they are 24v on a 12v system they will produce nothing other than a large spark if flashed with the wire. No spark, then you do not have a circuit.

Have you forgotten to re-engage the trip or reconnect the isolator switch that you turned off before messing about with the electrics? :giggle:

The old ones still energis but are intermittent in operation

Have a circuit ther gots not enigising

Could be a break in the wiring somewhere. Maybe not a complete break that's why it's intermittent.

I have two brand new ones and thay don't energize
Chances of two being faulty is verry slim.
The old ones are intermittent in operation that why I am changing them

Sorry can't help Bill mum was a dab hand with faulty starters, hope you get it sorted soon.

The resistances is almost three times the original one's

I only have a rudimentary knowledge of electricity Bill, but there'll be someone on here who knows about Ohm's Law or whatever it is, but it does sound like you've been given the wrong voltage units ?

Thay work on 24v I rigged up two battery's
