fixing a problem with my webasto

[David Anderson]

I have my 2010 wired on a 30 amp automotive type fuse with #10 wire, total length about 10'.  The unit runs all the controls and the pump through this circuit.  About 2 years ago it quit and I checked the 30 amp fuse and the socket was distorted from heat.  I replaced the socket and fuse.  Fast forward to today.  I checked the fuse and noticed heat stress on the spade.  

So, I ran another set of #10 (both positive and negative) wire from a spare fuse socket and mounted a relay on the pump circuit.  Now the Webasto only carries the load of the relay coil sans the pump.  The pump is on a dedicated fused circuit.  I'll watch it for a year and see if this solves the problem.  

Just thought I'd share my experience.

Is yours a 12V or 24V?  Thanks, BH

Dave,

I have encountered the same problem. My PO had the converter install the 2010(12V) curbside in the engine comp. with the 12V inverter batteries in the driverside aft bay. I had a large parasite drain until I found the 12 feed slightly melted,(?) causing a high resistance ground. I mended this. But, I believe I will relocate/replace this wiring from the front of the engine bay thru the rear cabin to the webasto with a larger wire size. Initially, I thought the wire failure was caused by the PO overheating the engine. The failure was just above the trans, but close to the block.
Later I believe this assumption to be incorrect. Been down that road frequently....

Hope this helps, Have a Great Day.

BTW, 1/2 - 1" of snow last nite, took me 75 minutes to get 12 miles from my office to home, 2 1/2 hours total travel (68) miles. NJ drivers can not cope with the snow.... If you even wish to consider that dusting as such.

With the risk of mentioning the obvious check the grounds and or give them good ones. I have seen that create these same problems on a Webasto as well as a Howard active steering unit. If the grounds go to a terminal block with other grounds moving it off  by itself cured both those issues.

Two Webasto units for our two buses and installed three more systems for others. I'm a firm believer in relays to control power to fans and pumps. I try to minimize the power run length. Using 12AWG for the power runs and 14AWG for the power to the control circuits. This supplies power to fan motors and provides signal to turn on circulator pump and Webasto start if necessary.
