12v Lights Flicker

7 posts in this topic

2001 Dynasty plugged into power and interior lights flicker. Originally noticed when just 1 fluorescent light was on. Turning multiple lights on minimizes the problem. Any ideas?

Is it a rapid flicker, or just dims for a second every couple of minutes?

If the latter, many chargers turn off charge (therefore voltage lowers) for a second or two so they can "sense" the true level of battery charge.

Hi Don, My first thought would be a contact(s) arcing on the 12 volt relay or solenoid. Depending on the way you coach is wired.Monaco has used both Latching Relays and solenoids often together depending on model and year of the coach.

One can disconnect fro m shore power and open the 12 volt battery grounds, then use a nail emery board to clean the contacts and see if that clears the problem.

If not, then one needs to look at other possibilities. so start at the simple and inexpensive first.

It is a rapid flicker. I have had the problem for about a week. Drove about 4 hours today and when initially hooked up to shore power the flickering lasted about an hour. Currently not flickering.

Sounds like it could be a 120 VAC (60 cycles per second) issue bleeding over to 12 VDC system.

Set your voltmeter to 120 VAC and check at the battery or 12 VDC outlet.
