Hi folks,
Hope you can help me diagnose this issue that I'm having... since I bought the MH, I've heard a little rattling issue coming from the passenger seat, I thought it was your typical plastic trim rattle as it would come and go and would vary on rpm.
Upon closer inspection, it's a relay clicking on the 12v side. Funny thing is, everything works but it's getting annoying and now it has turn into a constant clicking except for some rpm range.
I've been doing some tracing that that relay seems to be related to the alternator charging system as it gets both the leisure 12v and the alternator power and from there goes to the control board that feeds my control panel.
Alternator is sending a healthy 14.3v, checked all the connections and haven't seen any issues or drops it looks solid. Checked all the grounds and different connections and I either see the 12.7/8v of the leisure or the 14.3v of the alternator, the relay as I understand should close when it detects power allowing the 14.3v to charge the leisure but then open not allowing the leisure power go back to the main battery.
At the back of the van I noticed another relay that clicks at the same time which seems to be related to the 12v on the fridge, but it doesn't seem to be the fridge as if I unplug that, the clicking continues at the front. If I disconnect the power coming from the alternator the clicking stops of course. Relay doesn't seem to be the issue, tried with another one which while it was smaller in amperage, it was doing the same (have ordered a replacement just in case)
Checked all fuses, connections and all the ground wires I could fine all seems good so I'm a bit lost here... is it the control board going bad? what would it be the best way to determine this?
Good exercise to get to know my camper for sure but hope you can give me some ideas on what else to look for or test to perform to continue the process of elimination.
Cheers
Rami
