I was in need of a Prime/Start switch located on my Onan 4000 generator installed in my 2001 Pace Arrow. The paddle was missing. I removed the switch using a screwdriver. The information on the switch said, Carlingswitch, V801, 9939, Mexico, V8D1, 20A, 12V. With that information I tried looking for this part online. No luck so I contacted Carling by email giving all that information and it's dimentions asking if they carried such a part. Ernie Olson returned my email, email@example.com
. Ernie asked that I send him pictures of my switch so he could better identify it. I did so and he answered back it was a V8D1A60B-AEC00-000 and it was carried by their distributors, onlinecomponets.com and Allied Electronics. I went to their web sites and found the part ok but beside the $13 cost of the part and the $5 shipping they wanted and additional $50 because I only was going to order one. I turned to good old Ebay and using the part number Earnie gave me found the part at a total cost of $11.71 incl. shipping. So, if you are looking for this part I hope this information is helpful.
