The Brantz Retrotrip is a reasonably popular electronic/mechanical rally odometer that is used where average speed rally computers are not allowed and car owners are looking for an older style rally odometer. I have had a Retrotrip for a few years and have used it in several rallies. However I began to notice that sometimes the numbers would not advance when they should have. I did some testing and I discovered that this was happening with both displays, so I knew that I couldn’t trust either display. As this had happened to me, I also used a similar Retrotrip owned by a friend of mine in a rally and I discovered that the same thing was happening with his Retrotrip. I also found out from two other sources that the same thing happened to them.
The issue is that the counters, which are the mechanical part of the unit, will wear out. In an exchange of messages with Michael Bruns of Germany, I was told that the counters can be changed either by sending the unit back to Brantz or doing it myself. Therefore in order to restore my Retrotrip to a new condition, I decided to change the counters myself. This post describes how I did it and hopefully can serve as a guide for others.
You’ll Need a #10 Torx Screwdriver, Needlenose Pliers, And A Small Slot Screwdriver To Change The Counters
Remove the back cover of the Retrotrip odometer.
Remove All Five Screws From The Back Plate
The light shade on the top of the Retrotrip needs to be removed to get access to the top mounting screws on the counters.
Remove Top Light Shade
Once the top light shade is removed, then the two screws holding the counters in place can be removed.
Remove The Screws Holding The Counters In Place
The photo below shows the two counters. Note that they are manufactured by a company based in Brazil – Veeder-Root. The model number of the counters is important to note – 779185-207. I live in Massachusetts and I found a dealer in Connecticut, Walker Industrial, who imports and retails these counters. I am sure that there are others similar distributors throughout the country. Be sure to get the model numbers exactly the same.
The Two Existing Counters Appear To Have Been Built In May 2007
I ordered the two new counters and about 3 to 4 weeks later, the two new Veeder-Root counters arrived. The only difference between the existing counters and the new counters is that Brantz had added a decimal point to the clear plastic display cover to identify the distance to two places of decimal. I will have to add my own decimal place and the plastic cover that protects the numbers in the display.
One Of My New Veeder-Root Counters
As shown in the photo below, the two wires from the Veeder-Root counters are inserted in two connectors at the back of the Retrotrip unit. The wires from the existing counters can be removed from the connectors by depressing the little orange tabs, while pulling out the black wires. I made notes so I would not forget which wire went into which side of each connector.
Depress The Orange Tabs In Remove Or Reinstall The Wires From The Counters
The installation of the new Veeder-Root counters is just the opposite of the removal. It is really not particularly difficult. I should have shortened the wires coming out of the back on the new counters as I wound up cramming at lot of excess wire inside the Retrotrip box.
I want to thank again Michael Bruns who gave me the idea to fix the Retrotrip. I now am heading in a different direction with respect to older odometers, so I just might put my Retrotrip up for sale, but now I know that it is in “new” condition and I can pass it along feeling good about the Retrtrip.
