Merlo electrical problem

[tomildinio]

New to me merlo here. There is intermittent power to the main headlights. Side lights are OK. With the h7 bulbs out, the dash lights will work and do full beam on the dash. As soon as I plug in a bulb it stops working and the dash lights go out altogether amd may or may not come back. I am puzzled. Anyone know where this circuit is? Is there a relay? Fuses are all OK.

Tryed new bulbs give the holder a squirt of terminal cleaner

Tried new bulbs and cleaner but no power to bulbs again.

Found 4 relays under dash but not sure if that are legit or were added by a previous owner. Look a bit mad.

What model is it? It sounds like either an earth problem or just as likely plug melted on circuit board

Hey. Its a p34.7 plus. 2011.
I'll try the grounds. There is a big one on left of cab with the battery I can see.

I found 4 relays under dash too. One bypassed with a wire. But they don't seem to do much plugged in or out.

Non genuine modifications can send you wappy…

Got power back to the headlights with fiddling. I don't know whatbi did but there is only power to the dimmed connector but not the full headlight connector. If I put in the h7 bulb there is a click somewhere on side of machine and it's gone for about 5 mins then power reappears. I might remove the full beam connector and see what happens.

 

[tomildinio]

That did not work

 

[tomildinio]

Its the switch if anyone has any tips on hoe to get those in and out again.

Electrics are behind seat black cover fuses and relay

Strip dash but you will open a can of worms as I expect there is heat damage

 

[tomildinio]

I fiddled with switch without removing it so that i have dipped beams and put it all back again. I changed all worklights for leds to reduce load. I don't need anymore headaches!

The arm is now lifting up a bit or banging down when I crowd bucket back the whole way!

Lift ram lower bushes and possibly comp ram pin and bushes

 

[tomildinio]

I think comp ram pin and bushes for sure. I can see some movement on main arm pin too. Ram looks OK... it's a new to me machine. I'm not sure greasing was a top priority.
Is it a big job to change them out? Looks fairly straight forward!
