Roadmaster

July 12, 2012, 06:54:34 pm

Guess who has to wait 3 weeks for a base plate to be installed on my new CR_V. Its not Hitch pro-tows

fault, its Roadmasters, and like always they can never give a good answer.
Blue-Ox is even worse. So I

guess its hurry up and wait. Good thing I had planned on spending the next four week in Northwestern

Oregon. Frustrated.

My HDKAK 8kw Onan has started dying when the ignition key is turned on (10% of the time) or after the

engine is started (90% of the time). It make take 10 seconds or 5 minutes, but it always dies. I

systematically removed and then replaced the Xantrex RC7-GS remote, the Silverleaf engine monitor,

and the rocker start switch which eliminated all three when the problem continued to happen. When I

disconnect the cable at the genset, the generator no longer fails over any time period so the genset is
eliminated.

Here is where it gets heavy. In tracing the circuits, the generator start and stop signals (wires 159 red

and 158 brown respectively are normally high (12 volts). When any one of the three components,

inverter, Silverleaf or manual rocker switch connect wire 157 (ground) to wire 159 or wire 158 the

generator starts or stops (again, respectively). The only reasonable conclusion then is that when the

ignition is turned on, there is a gremlin conditioning that 158 wire with a false ground.

To test the theory, I monitored wire 158 (genset stop) with a digital volt meter. With the genset off,

there was 12 volts nominal on the wire. When I started the generator, the voltage on 158 dropped to
9.5 volts and stayed there, probably because it is a sensing circuit. Then
I turned on the ignition key,

but the generator continued to run. It only dies 10% of the time with the key. Then I started the engine.

Less than a minute later there was a negative spike (dropped to 4.5 volts) for less than half a second,
and the generator died.

Does anyone have a clue where that split second spike might be coming from? I doubt a short because

it come fast and predictablely, not like a bad ground or frame short would generally present. This just

started in the last year. It never happened before that so something has started to fail.

Well if you want to come on up to our shop we can install it for you next week, yes we're slammed like most shops this time of year..... BUT fitting a tow install into the line up is always do able. Had a customer yesterday call me in the morning saying he was looking at a new jeep and if he could make the deal happen could I get it hooked up by the end of today??? Well the Jeep showed up end of day yesturday & it'll be hooked up to his coach today.
And what do you mean Blue Ox is even worse? I (We) our both Blue Ox & Roadmaster as well as others, even us dealers that buy direct from the manufactures we typically buy most thru distributors & I just checked with 2 distributors and both have your baseplate for 2012 in stock both roadmaster & blue ox.
