[email protected] and I'll send you a copy of a fax I recieved from a 873 manual that has good information on this.
Mine turned out to be a almost severed wire from the steering lever harness, the 2 lights worked normal for 30 mins but then kicked into the alternate flashing mode (which disenguaged the hyd flow) as a result of resistance as the wire heated up.
It can be a bad contol box, new one for mine was $500.00 usd, it has the aluminum one behind the operators left shoulder under the cab. Look inside the ROPs hole where you check your hyd oil level, but on the other side, it has 3 wire harnesses coming from it, measures about 4 by 3 by 6".
The other option is a $175.00 box bolted to the inside of the frame by the hydrailic filters) and there is a 3rd option I was told) But it can be a broken wire or a poor conection in the harness, so hope for this.
It is not related to the BICS in any way
